he kind of is(a teenager). ever since his first rut in his teenage years, when he was told he slept with a dog, he has shut himself away from the world because of that trauma. that's why his personality sucks, his interpersonal relationships are so bad they nicknamed him a "mad dog". he has isolated himself so bad he doesn't know how to interact properly because no one can teach him because no one can come near him. he's only learning now because of josh, and in the future, when finds out he is a father, he starts to become more responsible because there is a child who has to rely on him.
You have a point here, I can’t disagree and Yesss I can’t wait for the chapter when he finally finds out he’s a father.
here we go again the same shitty classic when women are portrayed as crazy bitches in bl manhwa and Chase! Grow tf up man :| sometimes I question his alpha gender, I understand that he’s traumatized and hurt but this specific scene is giving “a teenager” not a grown ass man.
