"Mr. Yu, I like you so much!"
The male and female protagonists come from prominent families and are of the same family. The male protagonist and the female protagonist are of the same age. The heroine has known the hero since she was a child and has a deep love for her, but she has never expressed it.
So a two-way love started from the girl's one-way secret love.
Concept: Only love that goes in both directions is meaningful
