my father was abused physically and mentally by his mother (i will never call her my grandma) since he was REALLY young. it was SO BAD, my aunty told me. to the point my father growing up as a person who thought being abuse is a normal thing in romantic relationship. he even abused his ex fiancee.

but he changed after he met my mother. my mother is a straight forward and tough person.
my mum told me, the first few years after marriage were the toughest, but my dad followed my mum advice to meet therapist.
he was 'bad' with my siblings too. but we could hear him crying like crazy while my mum comfort him right after he beat up my sister and brother (i'm the youngest and he never touched me AT ALL).

but he slowly becoming a decent father and even getting better controlling his temper (after 20 years. yes. it takes a lot of time).
he never beat my siblings and mum anymore.
but still, i suffer mental illness while growing up because of what i witnessed and i do still meet psychiatrist till now.
but my father changed A LOT.

whenever we all go hang out together (we hang out EVERY week, never miss) he will sometimes smile and say to my mum, "if i never met you, i don't think i'm still alive right now".
he always say the same thing. hahaha.
and he always tell the same stories about how his mother abused him. seems like he can't forget about his bad childhood at all.

that's why, whenever i see character like this seme, i always wish he can meet someone who can change him. cause it's not impossible.
