When Shu Li, a student at the Academy of Fine Arts, met his senior Pei Yi at university, he felt an inexplicable sense of familiarity and palpitations, but he couldn't remember why this "stranger" knew his habits and preferences so well.
As fragmented memories continued to flash back, Shu Li gradually discovered that there was a deliberately forgotten past between himself, Pei Yi, and his late senior student Chen Zhi.
A car accident seven years ago took away Chen Zhi's life and caused Shu Li to lose part of his memory - he remembered everyone except Pei Yi, who was in love with him.
Pei Yi, burdened with guilt and self-blame, stayed away from Shuli's life under the threat of his parents, but always paid attention to him silently.
When fate reunited them in college, the buried truths gradually surfaced like undercurrents at the bottom of a lake: Chen Zhi's unspoken secret love, the fatal confession on the day of the car accident, the cruel barriers set up by parents to "correct" their sons' feelings...
Purpose: True love found in desperate situations
