A good shoujo. I appreciated the focus on friendship and the lack of mean-spirited competition between Wanachin and Simone. Eimi was a good protagonist and I also liked the fact that the other girls at the dorm were developed as well, and that there were no catty conflicts between them. Gotta appreciate Sawaguchi's subplot too, him rejecting Ichi (low bar, but still), and the lampshading of the Shoujo Confession to a much older man.
With all that buildup, it feels like the conflict between Wanachin wasn't actually resolved. It wasn't even...brought up when they met again, really. It felt weird, considering how much Wanachin didn't want his father to come to school for him, that he would just...sit down and have casual conversation with him like that, even if Eimi calmed him down.
The ending was abrupt, but now that I think about it, I feel that it would've felt off somehow if we saw them kiss or confess. At several points in the story I realized that I would've been perfectly OK with everyone ending up as just friends. Simone never came off as more than a friend to Eimi from the start, so her ending up with Wanachin was inevitable if the mangaka wanted to pair her up with someone; it was kind of frustrating to see him so hesitant in telling Eimi how he feels, though.
The oneshot chapter was kinda meh. Nothing that hasn't been done before.
8/10 overall.
