idk cus he's a weird guy?? My only interpretation was that it was from jajangmyeon because when the kid asked what happened to his mole he suddenly orders jajangmyeon and asks him to slurp the noodles as he holds it under his eye (where the mole was?). But the kid stops too early so it didn't work I guess and sends his home...Then in the latest chapter when the kid asked what the point of ordering jajangmyeon was, he makes him try it again but from the opposite way but because the kid moved his arm, it splashed everywhere on his check instead of it being a mole. I honestly have no idea but that's all I could think of.
Idk I feel like it's normal to eat jajangmyeon or anything with black/brown coloured sauce and mistake it for a mole or look in the mirror and be like oh I have a mole (in joking way). Otherwise why would he have pointed out to himself at that point that he had a "mole"? You'd either always had the mole and wouldn't point it out to yourself or if it did appear that day, you would've noticed in the morning.
Wait- so what happened to the dot under his eye/on his lip??
