Twins takes after their respective DNA donor toxic trait. Haejun takes after his father while Haeyoung his mother. Haejun is abusive self-entitled prick while Haeyoung is an overall doormat. Mother probably also thinks their father has no fault and pitiful for being thrown into the jail.
If Haeyoung is a girl, he would repeat the cycle. Juho would walk all over him while their children are watching but Haeyoung will get a ton of excuse why their father is pitiful and everyone must understand his circumstances just because 1 freaking night of interaction they had when he's a teenager.
