The Chu and Chen families go on a picnic. The groups go hiking, but the elderly lag behind. Chen then has a breakdown and admits to the Chu that her daughter does not want her to be around anymore, that she overheard the two parties talking about setting their parents up together so they would leave their families. Realizing his son can't live with him, Chu moves out in the middle of the night, leaving behind a note telling his son he intends to spend the rest of his life alone practicing self-discipline.
