Tear Jerker / In Your Arms Tonight

• In Ginnosuke's route, the protagonist makes up her mind to stand by Koichi, and Ginnosuke responds by bowing out and leaving the country indefinitely, he and the protagonist sharing a bittersweet farewell at the airport before his flight boards. All of this is already sad enough, but the real tear jerker comes afterwards, when Koichi - who has genuinely fallen in love with the protagonist and is doing his best to be a true husband to her - realizes that it's too late, and that her heart already belongs to someone else. As the protagonist apologizes in tears, he tells her that it's his own fault, and that if he'd loved and appreciated her sooner, he wouldn't have to lose her now.
• Koichi's route is particularly hard on the protagonist (and Koichi once the Break the Haughty has started to set in) but the moment that takes the proverbial cake occurs after the protagonist, Koichi, and his mistress have an explosive confrontation at a company hiking trip. The protagonist — already suffering from the emotional strain of trying to keep her marriage together and enduring Koichi's cold attitude — gets lost in the nearby woods and eventually trips and falls. Instead of getting back up or finding her way back, as she would've done earlier in the story, she finally breaks down and isn't even sure if she's laughing or crying.
• In Koichi's Another Story, after things really go south with the protagonist Koichi resorts to calling her at work at outright begging her to meet with him, promising to wait until she comes. She has no intention of showing up, and when it starts to rain an hour before the time he set, she's sure he won't be there either. Somehow, though, she ends up rationalizing her way into wandering out to the meeting place... and when she gets there, two hours after the appointed time, Koichi is there, standing in the rain.
