Tập 11: Keita, Ako và Riko chơi trò chơi uống nước với trân châu dẫn đến những hậu quả ngoài ý muốn.

11

Keita, Ako, and Riko play a game in which they exchange bits of tapioca between their mouthes. After realising that the tapioca juice was actually alcoholic, Ako takes advantage of Keita's drunkness, soon discovering that he possesses memories of the previous times he was intoxicated. Riko attempts to do the same, only to have it backfire on her. (Source: Wikipedia)
