The relationship with Kei-kun it's my favorite one... Yuu seems to enjoy it since the beginning of it, and accepted more naturally than in the others routes. The MC is always so bashful and self awareness but in this route he seems more concern about been in love, and in the others, looks like he is more concern about of who they are.
I'm a little bit confuse with day 29 and 30... the outburst could be avoidable somehow?
