MC wrote his home address on his hand, so that when he's discharged, he has some place to live, and also to take care of his younger siblings till he also gets discharged, and then all 4 (or 5 if you count grandma) live together .
Ok so he will stay with the white hair dude ok, and the other man? The brown haired dude? What happens to him? (Sorry I don't remember the names)
Hahahaha he's the worst brother in the world if he really sends this psycho to his family (but i feel like the uncle will now go after MC family, sooo it's probably for the better)
Myeong il solidified as the biggest bird of all time there’s no way this idiot did that
Wait wait, so, the mc loves the white hair dude? He confessed writing in the hand?
