That's My Number!!

In the beginning of Oresama Teacher, Mafuyu, a happy go lucky girl that used to be a yankee, finds a friend, Hayasaka, and takes his phone. She then calls him after seeing his number. But, the guy that he is, doesn't want her as a contact. But he's forced to take back his actions because of the guilty atmosphere.

What I really like about this manga, Oresama Teacher, is because pretty much every other page, if not every page, is something hilariously funny. Like this!
