Yatamomo
Momo is a useless, trashy, extremely bitchy guy with no ability to live on his own. Yata-chan is a caring, simple, and homely type of guy. One day, the two meet at a public bathroom as Momo is in the middle of "taking care of post-business", and from there on, Momo starts to take advantage of Yata-chan's kindness by crashing at his place. But as the useless Momo spends time with Yata-chan, he slowly begins to change.
