Thing is, Kogahara wouldn't Lemon to feel this way either and would immediately abandon any feelings she has for Sunao.
I think the ending is a no ending.
Kogahara honestly doesn't stand a chance because of the supernatural macguffin, and she was never going to once that was introduced.
Lemon's also in the perfect place to, even accidentally, fully sabotage any efforts on Sunao's part to get closer to Kogahara and ruin things for him. And if she lets her feelings get in her way
even once and make her lose focus, I could honestly see that happening.
And Kogahara deserves better than the setup she's been given, because she is
such a lovely character, as unversed as she is in all things romance.
Lemon's initial fuckup being repeated in this desire of hers to put herself last once more in the present with her feelings toward Sunao kinda makes it seem like she
hasn't learned from her past, and that in turn will only make all of this harder on all three of them - because she's had one important conversation with Sunao, but not
the important conversation about still feeling for him, and with Sunao and Kogahara tiptoeing around their mutual feelings for one another and only those on the sidelines being fully aware of the situation, it's all just set up for heartbreak for at least one of the three, if not all of them to some extent.
And I maintain that the BodySwapping
absolutely needs to be addressed in-narrative sooner than later, because they'll all but forgotten about it and just decided "this is our life now" and the longer that bomb is allowed to tick away, the worse the ultimate confrontation between them is going to be.
Because it's like Sunao's fully not thought about what happens if he
were to pursue Kogahara, actually confess and start dating her, and then....every other day wake up in the body of his ex?
That this hasn't been address in-story whatsoever (at least that I can remember) feels like a failure on the part of the author, honestly.
