Komaki slipped up and switched "stupid face" to "cute face," but she can't be blamed for that. The aquarium meetup was a sweet "date." Their feelings for each other have become so obvious that something has to give soon.
They're acting like more of a couple than most series' MCs could ever do; and what a heartfelt hug. I'm waiting for what reveals Komaki's real feelings, since Wakaba seems like she'll never get it. To be fair, Komaki still doesn't understand that Wakaba loves her too. They're silly.
