Yaoi uke dad

Is there anyone know bout yaoi manga where, the uke, one day a woman burst into his house and claimed that he has a son with her before, for some circumstances IDK what's the reason, after entering the house just like that, the woman told him to take care of their son for a while cuz IDK maybe she got a business trip...

The son looks like maybe highschool teenage or bout twenty IDK cuz this I read this manga so random before...

His son like his father even though they just met for the first time ever, IDK if he's really his son by blood cuz the story is short... And his son physically his body looks big and tall than his skinny dad

If anyone know pls tell me, I want to reread it back so I can understand it ^_^ I don't remember the title huhu

P/s: IDK if this manga is incest or what cuz I don't remember the whole story that much, I read this like years ago when I was a teenager maybe more than 5 yrs ago huhu, BTW the uke is the dad, and the seme is the son
