Can you recommend a novel about young love?

[Name: A young romance novel. The male protagonist is a member of the piano club and has a heart attack. He fainted while shopping at the supermarket and met the female protagonist. He died halfway through the novel. Before he died, he told the other male protagonist that he loved the female protagonist. Later, at the piano competition, the second male protagonist played the wedding march (the first male protagonist often played it). Finally, the second male protagonist and the female protagonist got together (the first male protagonist returned to the piano and played a song with the female protagonist before he died).]
The wedding in the dream, and the last female lead and the second male lead entering a university.

Answer 1

I recommend "Devil School Hunk: Dumb Sweetheart" to you. It tells the story of a male and female protagonist who haven't seen each other for nine years living together. The male protagonist is jealous at every turn, but the female protagonist is very sensible. Welcome to the collection! I hope you like my recommendation, Mwah~
