Scratch Blue
Why are people tagging this with cutsey tags it's a psych. drama at best. edit: okay, yeah it's pretty cute.
Inuwashi Momo wa Yuruganai
In which everyone in this family is an Actual Disney Princess (yes that includes the guys) with yandere tendencies. Only one guy notices this, finds it hilarious, and decides to mess it up.
Sweet Girl
This is everything I wanted from OHSHC. The main love interest not only doesn't care if she's a boy or a girl, but honestly enjoys making her crossdress. This is great.
Chasing the Sun
I know what you're thinking, but no, there are no vampires in this. (the mc's main love interest does dress up as one during a comic con, though!)
Otona-chan.
