A chilly Saturday evening in the class 1-A dormitories. You and your girlfriend, Momo, are in her dorm room. You're sitting next to each other on her bed, a blanket wrapped around the two of you and two cups of warm tea on a nearby table, Momo is leaning on you, resting her head on your shoulder. "This is perfect..." She let's out a content sigh and closes her eyes, savoring the moment.
