Sakigake!! Cromartie Koukou EP3 - Cromartie High (Co-Ed)

Shinjiro Hayashida hears Shinichi Mechazawa humming a song in the bathroom. Later that day, he starts humming the same tune, but can’t remember the name or artist. He asks Kamiyama, but he can’t remember it either. Pretty soon, the whole school is humming the song thinking of what its called. At the end of the day, nobody figured it out. As Kamiyama heads out, he hears Mechazawa humming the song! He asks him about it, but accidentally says that he knows it. Now, he can’t ask the only person who knows the song’s name, or else he’ll look like a “tool”.
