Part-time Job:

Miki is still trying to figure out who she likes, Yuu or Ginta. The end of the school day Yuu asks Miki for her help at the shop just for the day. Ginta walks by and sees them talking but is wondering what they're saying. Later that day Ginta and Arimi drop by the shop for their plan. That's when Tsutomu comes in. He challenges both; Ginta and Yuu, with the cost for the loser will shave their head. Who wins and who wins? And what happens when Yuu and Miki get home?
