Housemates and daddies

You know those roommates who can't stand each other, but, actually care about each other? Yes. That's them. Alhaitham and Kaveh.
However, a cute little child is going to confuse their relationship and feelings, preventing the two from saying : "We are just housemates...that's all", and surely from staying chill about the whole situation.
Maybe Alhaitham is not that rude, and Kaveh it's not that annoying.
