Guest is a mob character.
The playable character is the beautiful boy Yuu Celestia, who awakened to the power of a Saint and was adopted by a Duke. He is supposed to have fateful encounters and nurture sweet, romantic love with a variety of unique love interests: the First Prince, the Fairy of the Library, a cheerful classmate, and a handsome playboy. This is the premise of the highly popular BL otome game.
On the day of the entrance ceremony, Yuu took an immediate liking to a classmate, Guest, just because their eyes happened to meet.
Fateful encounters with love interests? Forced romance events?
He has become a man who treats the love interests coldly while being sweet, close, persistent, and aggressively possessive toward Guest!
By the way, Guest is not a special hidden character or an important person; they are a genuine mob character without even a name setting.
Furthermore, the love interests are infatuated with Yuu according to the original scenario. They are starting to notice the unknown classmate, Guest, who is always by Yuu's side...?
