Ep. 4: Chika e Ryota lidam com incidentes escolares envolvendo água, leite e debates sobre a retirada de camisas.

4

At the conclusion of a watery P.E. lesson, Chika and Yūki find Ryōta struggling to wash the chlorine from his eyes as he is scared of the water burst. Having had to deal with Ryōta's resulting complaints, Chika attempts to intervene until their friends interfere. Later in class during lunch, Ryōta accidentally empties a carton of milk on Megumi and drops his overfilled soup bowl on Yūki. On his way to the nurse's office to apologize, he instead discovers Natsumi sleeping after being stripped by Megumi and Yūki for a change of clothes and is subsequently beaten by the two when they return. At the end of the school day, Ryōta 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 Kōji's question on their relationship, Ryōta emphatically declares that he and Chika are only childhood friends. Anguished upon hearing him say so, Chika unsuccessfully tries to trick Ryōta into kissing her. (Source: Wikipedia)
