What will you do when you meet someone you loved back then five years later? A grand two-way secret love, unknown to both parties. Five years ago, Shen Jiaming disappeared into Chi Jin's world. Five years later, the two met again because of a wedding. After their reunion, her words about "Long time no see" made him take off all his guard. He still likes her. You are my preference without exception, and I just want to give you the unique love in the world.
Concept: There is always someone who will let you know that secret love is not bitter, but very sweet.
