In the first game, if you take the time to learn about Shiva during the Dating Sim segments. We learn that Shiva is a girl born of a one-night-stand between the former emperor and Shatyarn. The ensuing scene where mother and child are able to address each other as such for the first time and share a tearful embrace can bring tears to many eyes.
In Milfeulle's route, Tact shows he's willing to put up with all sorts of random crap just to make Milfeulle feel like she's not completely bad luck.
In Ranpha's route, managing to do the impossible and buy Ranpha a pair of shoes that aren't for sale, and then doing the impossible again by managing to salvage Ranpha's evening despite the shoes she herself demanded being too big and Ranpha feeling like she personally ruined everything.
Also on her route, after a misunderstanding causes Ranpha to think Tact isn't interested in her and she locks herself in her room to cry, Tact brings back the diary she gave him and decides that, if he can't write his feelings for her, he will say them out loud. He proceeds to say all the things he likes about Ranpha and shouts out loud that he loves her and wants to be with her.
In Mint's route, by the skin of his wits and by his love for Mint, he manages to rescue Mint from being imprisoned in her own home by her father, and repair a father-daughter relationship that had been estranged for years, in one single Big Damn Heroes scene.
In Forte's route, once it's determined that the Happy Trigger has the highest chance of successfully destroying the enemy satellite and clear the route for the Elsior to the White Moon, Tact fears for Forte's safety and doesn't want to let her go. Forte's subsequent Declaration of Protection for the man she loves is what convinces him to trust her, and in turn he promises to protect her as well.
The manner in which he deals with Vanilla's agony and grief after her beloved pet rabbit, Ugiugi in the Japanese version and Bunbun in Aroduc's translation, dies is near saintlike; he says all the right things, manages to deal with all of Vanilla's underlying demons in the space of a few minutes, and is completely respectful to what is essentially the death of a pet. Vanilla's reaction to his handling of the situation is to ask him if they could stay "like this" (holding each other) a while longer. That's right, by virtue of his sheer niceness, Tact managed to get a 13-year-old girl from sobbing her eyes out over the death of a pet to shyly asking to prolong a hug. Even if this weren't a romantic route per se, and it is, the scene would still be heartwarming even if Vanilla was just Tact's sister or daughter or something.
Galaxy Angel Moonlit Lovers
In Ranpha's route, Tact intentionally makes a complete ass of himself by dressing up in a Ranpha-fanboy-outfit and doing an extremely corny love cheer, just to prove to Ranpha that he's perfectly willing to keep up with Ranpha's fast pace and romantic over-enthusiasm if that's what it takes to love her.
In Forte's route, one of the first things we see Tact do during his break time is to look up dance halls where he can take Forte, as they couldn't dance at Fargo. Of course this makes her happy, but Tact takes it even further because he wants to pay for the entire hall just so they can have it all for themselves.
In Chitose's route, Tact clears up Chitose's trauma over her deceased father in a single scene so she won't pointlessly sacrifice herself against Nefuria in the GA-007 and so Chitose will allow Tact to be with her.
Galaxy Angel Eternal Lovers
In Ranpha's route, risking his life to save Ranpha from a burning building by catching her as she jumps, which permanently erases Ranpha's previous traumatic reflex of striking Tact whenever he touched her.
In Mint's route, Screaming "I LOVE MINT!!!!!!!!!" into the Elsior's loudspeaker at the top of his lungs so everyone in the entire ship can hear him, and then launching into a loud speech about how much he loves Mint, how much he wants to hold her close, and kiss her all day long, and all of that just to wake Mint from an "exhaustion coma" caused by her romantic turmoil. It works, although Mint at first gets pissed off at Tact for saying embarrassing things like that for the whole ship to hear, but Tact was clearly willing to pay the price of Mint being mad at Tact for a few minutes to make sure Mint's all right.
Later in the same route, managing to find Mint buried in rubble and rescuing her after they had an argument over Mint's emotional shyness and sudden distance, by managing to hear Mint's voice when no one else could. Another Big Damn Heroes example, just like in Mint's route from the first game.
In Vanilla's route, he teaches himself to knit to prove his love for Vanilla. Then he tops himself by proposing marriage in a manner that clears up all Vanilla's romantic fears at once and causing her malfunctioning nanomachine pet to return to normal. Then he tops himself a third time (although this one's not stated directly, the player has to make an inference) because when he gives Vanilla an engagement ring, her name is engraved on it. That means Tact can't take this ring back to the store because it technically counts as "damaged," his commitment is permanent, despite Vanilla's still-too-young-age. Clearly Tact is willing to wait.
In Chitose's route, after a lot of false attempts, Tact and Lester finally manage to figure out a way to break Chitose of her delusion that she loves Lester. It turns out they had to do it in stages (Tact and the Angels were trying all-at-once zany schemes before like writing love letters and romantic re-enactments); first Lester has to explain to Chitose that he's not her boyfriend, and then Tact has to finally bite the bullet and do something he's been avoiding out of sheer nerves: tell Chitose flat-out, to her face, that he loves her and wants her to go out with him. That doesn't really seem very heartwarming, but it does reflect Tact's usual tendency to be willing to put himself out on a limb for the woman he loves.
The "kiss scene" in the simulated park at night against the stars in Milfeulle's, Vanilla's, and Chitose's routes. It's the "first kiss" for Vanilla or Chitose, and in Milfeulle's case it's not their first kiss because Milfeulle already had her "second first kiss" earlier in the game back when she still had amnesia. There's no "kiss scene" in that spot with Ranpha, Mint, or Forte, but their scenes are just as heartwarming: Ranpha doesn't get a CG but the conversation is romantic, Mint allows Tact to lay his head in her lap, and Forte and Tact converse about their future over drinks. This moment, whether kiss or conversation or laying down or drinks, is even more heartwarming considering that in Eternal Lovers, Tact had to go through hell just to prevent his relationship with chosen Angel from ending for good. That's why this game is called Eternal Lovers.
On every route, before heading off to the Val-Valross system for the final battle, Tact and his chosen Angel share a scene with Lushati, who wants to apologize to them for all the trouble she (unwittingly) caused for their relationship, as well as the fact that she can't bring herself to hate Wein despite everything he did. Tact and his girlfriend assure her that there's nothing to apologize for, and they're actually grateful for it because, through Wein's sacrifice, they realized that perhaps not everyone among the Valfask are evil, and now they're determined to win the war not to wipe them out, but to save them so they can coexist in peace one day. The sequel proves their hope was not misplaced.
The moment when Tact finally proposes marriage! In Vanilla's route, it makes Vanilla so surprised-but-happy that her malfunctioning nanomachine pet returns to normal. In Milfeulle's route, it happens near the end, and it actually takes Milfeulle a few seconds to register what Tact just said. Then Milfeulle blushes like crazy and stammers a lot, but she joyfully accepts. Ranpha gets an indirect marriage proposal; Tact wants to meet Ranpha's siblings since they'll be his future in-laws. It takes a second for Ranpha to get it, but the only way her siblings could be Tact's future in-laws is if Ranpha married Tact. There's no formal marriage proposal in Mint's, Forte's, or Chitose's routes (Mint and Forte just kind of take it for granted that they'll be together forever with Tact and that that implies marriage, although Mint is much more affectionate about it than Forte, and Chitose's romantic relationship started really late since they didn't even officially "get together" until the third game, so Tact and Chitose end up starting to date instead, but they still end up married by Galaxy Angel II).
Tact and Lester have come a long way since their patrol fleet duties from the first game. While Lester's chastising of Tact has become commonplace, the two take a small moment before leaving for the Val-Vaross system to reflect how far they've gotten together and how they got each other's back. Lester is actually impressed enough with how love motivates Tact so much that he off-handedly mentions that he wouldn't mind trying it out one day.
The PS2 re-release of Eternal Lovers came packaged with a few extra CGs, particularly three CGs for Almo and Coco finally getting some attention as well as Dr. Cera and the engineers.
The PS2 version also got a brand new song for its ending, titled Endless Prelude. A song so passionate that the singer, Hiromi Sato, apparently cried during and after recording.
