That's just the little to no respect he has for Jun and Ji-hwan.
yeah i agree
My exact thoughts. Though his manner of speaking may be "calm" as Jun thought in his mind, his actions speak volumes and show the level of disrepect he has for Yul's guardians. You don't even notify them and just go up to the kid like it is nothing and expect everything to be fine and go your way. Get your head out of your ass bitch. Ypu may be Yul's biological father but you are not his real father/ parent.
exactly, i guess we can expect a fight between jihwan and that bio father, when jihwan learns about this.. and even jun will probalby get angry, and it they don´t get upset over it which they should, then there is something wrong... but lets see what will happen..
going to the daycare without informing jihwan first was a bad idea even if you are yuls dad
