Become So Tired || Seongjoong

Park Seonghwa has three rules he lives by that have kept his life as easy as it can be as a single parent of two:

1: The kids come first.
2: The apartment stays clean... Always.
3: No dating. No exceptions.

Kim Hongjoong has his own set of rules for himself and his sons:

1: There are no rules.

When Hongjoong moves in next door he challenges every aspect of Seonghwa's parenting style. His life quickly becomes filled with sticky fingers, unpredictable bedtimes and McDonald's for dinner. And with Hongjoong's guidance, Seonghwa starts to realize that maybe the rules are meant to be broken... At least under certain circumstances.
