Wait so incest?
By any chance, do they live together and the mc is the one doing the chores or something?
The story looks interesting
Oh never mind, it's his step nephew

yeah the story is similar to that manhwa
Yep this one! Tysm :D

It's yaoi and the story goes how the sister of mc married this man and that man also had a son. So the mc became the uncle for that son and they got together. For more details the boy aka the son has blonde hair and the mc has black hair. hope you guys can help me :) i want to reread it and if I'm not wrong it's completed!
