Just When You Think It's a Hanky-Panky Episode
Rentarō proposes a game of Old maid to get Shizuka broken into the group, with the added penalty of the loser getting tickled by the winner. He wins the first three rounds, with each round leaving a different girl in last place. Shizuka wins the fourth round, but only goes about gently poking Rentarō. Sensing hostility from Karane, he steps out to let the girls talk thing out among themselves. Karane tells Shizuka that she does not need to hold back because she is just as loved by Rentarō as the other girls. When he returns, Shizuka decides she is ready for a kiss with him.
