The big confession from the main protagonist! Long awaited for manga readers to see animated. While Rin's initial confession could have been better, it was still cute to see a teenage boy (sort of) confess to his crush. And the humour of his brother doing his own little "self-discovery" while Rin was with Shiemi was on the opposite spectrum, it was honestly quite humourous to see the "calm, collected brother" try to conduct his own experiments instead of asking for help. The episode did a good job of highlighting how the brothers deal with their issues as a person and the conclusions they come to. (One chooses companionship and the other solitude).
