Let's Hot Spring!

While shopping with Chitose at the local shopping arcade, Choco wins a free trip to the Hot Springs for 4. Choco chooses herself, Haruma, Chitose and Makoto to go. After a rehearsal bath at the public bath with Choco and Makoto, Makoto gets a call from her job while at the train station and she ends up not getting to go. Choco, Chitose and Haruma travel via train to the hot springs. When they got there they went to the baths. Haruma found out that it was a shared bath and he tried to hide from Choco and Chitose but after staying in too long he got up dizzy and as he was walking out Chitose saw his private places. That night Haruma couldn't sleep so Choco held his hand so he could.
