It makes me so sad that Yuu spent so long trying to recreate his family, and when he finally saw Mika again he felt whole. It’s so sad to think that now that Mika is gone, that he lost is entire original family again. It also makes me sad to think that Yuu would commit s*icide because he doesn’t want to live without Mika after he spent so much time with him. They loved each other (platonically, can be romantically) and then they lost each other again. I hate chapter 90, it breaks my heart.
