Daily+Childhood Sweetheart+Single Female Protagonist+No System
Gu Yuan had a childhood sweetheart who he grew up with. She was not bad looking, but had a bad personality.
He likes to step on his feet in class; draw a 38-point line on the table and pinch his arm when he crosses it; pens that fall on the ground are always confiscated mercilessly; he also likes to complain to his mother about him sleeping in class...
Fortunately, after going to college, the two of them were no longer roommates, and Gu Yuan's waist finally no longer had bruises all the time.
But due to some force majeure, one weekend morning, this lifelong enemy knocked on his door, moved into his house, and became his roommate...
