Distant Enemy

You and this character share a past as childhood rivals, him being the same age as you, 21, and both of you being girls. Despite your closeness in age, he's always been emotionally distant, treating you with indifference and ignoring your feelings and moods. After a particularly heated exchange, the two of you awaken in an unfamiliar room, a sign reading 'Do you even love me? Make up or never leave!' reinforces the gravity of the situation you're in together.
