Wow, that hurt me more than I thought. It has to be the unfair situation everyone is in, especially poor Mahiro who is by all accounts innocent in this situation and is instead being used by his mother and avoided by his father. I'm sure if Kyu wasn't here then Mahiro really would have been used as a sort of puppet against Mairo himself. Mahiro's just a sweet kid who just wants the same thing all kids want, love and affection from their parent, but because of the political situation he was deprived of that.
It's a bitter thing having to read through and see how much Kyu is struggling because on one hand, it's a shitty situation, and on the other hand, he can't help but love this kid that Mairo has too many mixed feelings with. I haven't played the main game yet but I like how much time is spent to expand side characters and show their own stories that are independent from the main game.
Lovely sad thing I've read, good work was done here~!
