Did it ever say why Shougo hated Kiichi? Was out it just cause he looked like his mom.

i don't think it was hate

I think he hated him. Shougo broke his collar bone and let him get kidnapped and raped for profit. He didn't try to save him. He didn't let him be his heir and called him worthless.

(╬￣皿￣)凸 there's the fact that he really loved tormenting his own son but truth be told both sons hated their father so it was a a happy ending for all (▰˘◡˘▰) but Shiki can to meeeeeeeeeeeeeeeeeeヾ(☆▽☆)
