People blame Seto, but I think Anna is just as much to blame. Whenever she actually gets serious(Ex: the “why don’t you fall for me for real” line), she ends up following it up with “just kidding” and things like that. Somebody with low-confidence like him isn’t going to just pick up on hints. She’d have to just explicitly say it, and that’s why I think she’s just as much to blame, if you really want to blame characters. But I’m completely fine with how it is now and I think they’ve both progressed lately.
