"How to kiss like an adult" is the first line of the play, which begins with Hiroyuki's brother, Nemo, asking Nemo how to kiss a girl. Nemo tries to get Nemo to kiss him, but he can't seem to do it. Nemo asks Hiroyuki how to squeeze his nipples, and Hiroyuki says that it's impossible. Nemo is so excited that he tries to stop the kiss, but Hiroyuki won't let him.
