Why do small apples like old pineapples?

The old pineapple helped the little apple.

The little apple and the old pineapple are the characters in the movie breakup guru. Because the old pineapple helped the little apple when she was down and out, she regarded gratitude as love.

Breakup guru tells the story that "breakup guru" Yuangui Mei met Xiaochun Ye, a strong woman from Beipiao, in the process of "breaking up" to start a business, and thus staged "the stupidest but most touching love comedy in history".
