AverageWeirdo's manga / #age gap(77)

"Seoyu is an extremely recessive omega who can't believe his luck when he meets an extremely dominant alpha named Sunghoon Choi. This alpha has it all, even if he might be a gang leader! Seoyu intends to enjoy their fling for as long as he can because that's all it is, right? Sunghoon can't possibly be interested in being Seoyu's boyfriend. However, he does boyfriend-like things, like having meals delivered to Seoyu's apartment and constantly worrying that Seoyu is too cold… but surely this is just temporary!"
