On Lin Zhu's 18th birthday, Jiang Yu gave her a set of professional paintbrushes, saying they were "a birthday gift for my sister." However, Lin Zhu later discovered that the set of paintbrushes was a style he had casually mentioned at his best friend's house that he "wanted very much but was too expensive." When Jiang Yu was 26, he posted an "unfinished architectural design drawing" on WeChat Moments, with a corner of Lin Zhu's sketch in the background. No one paid attention at the time, but it later became proof that the two of them had the same mind.
