In which episode did clannad of Apricot Tree put Yun's hand on his?

This scene appeared in Clannad (the first season of Clannad) episode 18 "The Secret of Return" (the secret strategy of return).

The main reason is that Peng also had a good time with the Fujimori sisters during the three-day suspension. When playing the divination game, Apricot puts her hand on Ye Peng's hand (this is also an important part of Fujimori's sister route in CLANNAD game, because Apricot should make good friends with her before the branches of Apricot and Apricot appear).

I hope I can help you.
