I have to agree with SeijiSensei... the grandfather turning out to be a pervert was a downer for me, though I suppose it explains why Kotoura isn't that bothered by MANabe's antics? Regardless, it feels weird.
Speaking of feeling weird, how exactly did MANabe turn into the bad guy? I'm actually glad he didn't go "I forgive you
Let's be friends!"...his reaction's a lot more believable, even if I feel he's not likely to hold a grudge. On the other hand, Kotoura forgives too quickly.
Pretty standard episode. Enjoyable nonetheless.
