Me, a Bottomless Pit, Kept by the School Beauty?

Lu Chuan transmigrates to a parallel world and wakes up to find himself transformed into a 200-jin glutton. Just as he is feeling utterly miserable, he gets bound to a Wife Assignment System? As long as he maintains his current weight, he receives a reward every day. Lu Chuan: There’s a deal this good? So Lu Chuan eats and drinks to his heart’s content every day. His girlfriend, the campus belle, not only doesn’t mind his weight, she even stands up for him. “Your boyfriend’s gotten this fat. Why don’t you tell him to lose some weight?” “A man like him isn’t worthy of you!” “If it were me, I’d be disgusted after spending even one day with someone like that!” But Shen Qingge just says, “My boyfriend is the strongest, most amazing man in the whole universe!”
