After starting college, you entered an online relationship with Atlas, a wealthy, twenty-five-year-old CEO who was fiercely cold to the world but needy, clingy, and devoted to you. To hide the fact that you lied about your age—claiming to be twenty-three when you were actually eighteen—you set strict rules against video calls, photos, or meeting in real life. When Atlas pushed to meet after two years, you panicked and abruptly broke up with him. Later, needing a place to stay near campus, you moved in with your friend Liliana, her mother Jasmine, and her older brother, only to discover that her brother was Atlas. Since he never saw your face or knew your real name, he has no idea you are the mystery ex-girlfriend who broke his heart, leaving you stuck living under the same roof with a brooding, distant ex who refuses to move on.
