isn't the happiest manga out there to start with, but there are still some extra tearful moments
Koshiro: "I don't plan on trying to contact you again. This is the last time we'll be together like this."
- She closes her eyes and lifts her tear-stained face to Koshiro and he ... kisses her on the forehead, says "Goodbye" and starts to walk away. She yells "Unfair!" to which he responds "Just appreciate it." Before he walks off, she wipes her eyes, gets his attention one last time and gives him a happy smile and waves goodbye, then turns and runs home with tears streaming down her face.
- Koshiro and his co-worker wind up in a store that sells wedding dresses with Nanoka tagging along. Nanoka is persuaded by the oblivious co-worker and the shop-keeper to try one on. Koshiro is stunned by how beautiful she is, while also knowing that this is the only time in her life she will get to wear one if they keep their relationship. Then, they get their picture taken next to each other, as if they were bride and groom. Nanoka keeps the picture in her journal and looks at it often.
- Koshiro makes up his mind and tells Nanoka:
- Which is his way of finally telling the rest of the world to go to hell about their relationship
Nanoka: "If I could be reborn, and not be your sister ... so then ... I could be your bride."
- The ending, where Koshiro and Nanoka decide to go ahead with a romantic relationship. They may be happy, but it's clear they still have a long and difficult road ahead of them. And in the manga, the last couple of chapters has Nanoka admit that one of her childhood dreams was to get married and have children, and that will probably never come true in exchange for what she really wants.
- The scenes of Chidori trying to convince Koshiro and Nanoka that their relationship has no future and is not right. She might be abrasive about it, but she does have a point.
