Bizarrely innocent and twisted/kinky at the same time. Hibiya's best friend Mirai wants desperately to reflect sincerity in all things and so begins a string of questionable relationships with men who push their feelings onto him. Hibiya tries hard to keep Mirai from getting hurt, but begins to suspect his own feelings are less than pure. I think Yoshida Yuuko thinks this story is a happy one, but I can't help feeling like she wasted the set-up, especially past chapter 3. Mirai is too pure for this world, in a literal sense -- he becomes an intense mirror of the feelings of the people around him, and it's impossible for anyone to handle that kind of unadulterated sincerity. The decisions Mirai makes are laughable, because he seems to operate in a world where no one can have bad intentions.
Hibiya rightly recognizes that the only way to save Mirai from himself is to ruin the very thing that makes Mirai himself -- teach him to lie, and teach him to see that others lie, and that you can't just accept other's feelings for you unconditionally. Hibiya is at cross-purposes with himself, too, because teaching Mirai to see past veneers will allow Mirai to see that Hibiya is possessive and lustful, and this all gets twisted into a weird bundle of poor decision making on everyone's part in chapter 3 that is honestly suspenseful and exciting. But then there's this slow slide into predictability in the last chapter, where Mirai's innocence isn't treated like the bomb it's been in the earlier chapters and reverts back into bl tropes of the uneducated, bashful uke who can't understand his own desires. Interesting, but disappointing, which was my feeling about Yoshida's other works as well. In some ways, this is the lighter Toujo Asami, who trafficks very much in the same kind of relationship dynamics and intense, unbelievable main characters.
