Yuu-senpai's record is called "Hypocrite," huh?
Hmm...
Honestly I would be shocked in Yuu wasn't in love with Minori and that's part of the reason why she puts up with antics. Given how flustered she can be around Minori and if you take Minori gushing about little girls as jealousy instead and took into account the whole drunk kissing thing... I dunno. I think if she is, she decided not to act on it or let Minori know.
Also, Yuu-senpai/roommate is best girl.
