Ryuuichi Falls Ill, Kotarou Steps Up!

Ryuichi is in high school now. He takes the daycare gang around to see the school's clubs, which are recruiting. He also tries to get people to join the babysitter club, but it doesn't seem to be going very well... Later, Ryuichi gets sick, and has to stay in bed. On the chairwoman's instruction, Kotaro works hard to try to make Ryuichi a special drink that will make him better.
