Tear Jerker / Kaitou Saint Tail

• The Oblivious to Love treatment on both ends effectively makes it hell for both Meimi and Asuka Jr. for an extended period of time as they both continually fail to notice each other's feelings, all while suffering.
• Asuka Jr. seeing Meimi in Saint Tail's reflection in chapter/episode 13 is especially played this way in the manga version, where his expression looks completely shattered as he parses the implication that the girl he's been developing a crush on might also be the thief he's been charged with arresting, along with all of the other uncomfortable implications that comes with. It's no wonder he has to rely on Selective Obliviousness to cope afterwards.
• Chapter 15/Episode 23 is both the chapter/episode that properly reveals the full meaning of the flower-and-snow Creation Myth and the chapter Meimi starts actively pushing Asuka Jr. away out of fear, making the immediate contrast between her mention of "the flower that could be near the snow" (i.e. her feelings of wanting to be with him) before pushing him away even more heartbreaking.
• Chapter 19/Episode 29 has Asuka Jr. staring at Saint Tail with an expression that's somewhat difficult to read but has a very clear sense of longing (this is particularly clear in the manga version of the scene, where you can see the pain very visibly on his face). At this point, he's in a very difficult state with his complicated feelings about potentially losing Meimi, his subconscious suspicion that he's actually looking at her right now, and desperation to get a proper answer to all of this... but not only is he forced to let go, Saint Tail also still thinks he only wants her to stay so he can arrest her.
• Meimi's severe insecurity hits peak in chapter 21/episode 40 when her utter misinterpretation of what Asuka Jr. had told her in the previous chapter/episode leads her to believe that he'd found some other girl he'd fallen in love with, meaning that Meimi is so unwilling to believe he could ever love her that she has an easier time believing he'd found some unnamed girl with some accidental resemblance to Saint Tail. Which is only made worse by the fact that in a later bonus manga chapter, even after everything is settled, Meimi is still convinced that she's just some inferior version of Saint Tail to him, meaning it really is that hard for her to register the idea that he can actually love her.
• In the last chapter/episode, Asuka Jr. wonders if Meimi was enjoying the idea of messing around with him, based on the fact he'd just learned from Rosemary that Meimi had actively wanted to hide her identity from him for some unspecified reason; firstly, this confirms that Meimi's fears about him hating her purely for deception were largely unfounded and that this would have been solved much earlier if she'd just told him, and secondly, it suggests that, Asuka Jr.'s infamous denseness aside, he has an easier time believing that Meimi was using his suffering as a coping method than the more obvious alternative.
