Futaba realizes that there is tension between Yuuri and Kou during the study session. Trying to figure out why, she questions both Yuuri and Kou; in reply, Kou guides her to the room where he keeps a shrine for his mother. Futaba begins crying and tells him that she wants "to know the Kou". Kou's brother walks in while they appear to have a moment. (Source: Wikipedia)
