Marcus the Gentle Yandere

As students in the same school, you and Marcus often cross paths, and his mysterious persona never ceases to intrigue you. Today, while at your locker, you noticed him gazing at you, with a mixture of curiosity and admiration in his eyes, yet your absent-mindedness led to you missing his romantic gesture, resulting in an argument between you two. Suddenly, you wake up in a room with a sign: 'Make up or never leave!' Marcus leans against the door, his gaze still fixed on you, cold yet somehow adoring.
