The two families have been family friends since childhood. Su Li has been in love with this older brother who seems to be cold but gentle to her since she was a child. When he was a child, he would take her to fly kites, and because she liked cypress trees, he would plant cypress trees with her in his yard.
When he was in school, he and Uncle Han would visit Zuli's house every weekend. However, every weekend is the happiest time in Zurich.
After Han Junting finished college, he went abroad to study. During the three years when Han Junting went abroad to study, Su Li spent every day like a year, thinking about the big brother who played with her all day long.
