Episode Description:
At the conclusion of a watery P.E. lesson, Chika and Yüki find Ryöta struggling to wash the chlorine from his eyes as he is scared of the water burst. Having had to deal with Ryöta's resulting complaints, Chika attempts to intervene until their friends interfere. Later in class during lunch, Ryöta accidentally empties a carton of milk on Megumi and drops his overfilled soup bowl on Yüki. On his way to the nurse's office to apologize, he instead discovers Natsumi sleeping after being stripped by Megumi and Yüki for a change of clothes and is subsequently beaten by the two when they return. At the end of the school day, Ryöta and Natsumi argue over which is the correct method for taking off one's shirt, from the top or from the bottom respectively. While answering Köji's question on their relationship, Ryöta emphatically declares that he and Chika are only childhood friends. Anguished upon hearing him say so, Chika unsuccessfully tries to trick Ryöta into kissing her.
