I'm sorry Miya, you totally neglected your father for 1 years, leaving him with literally no emotional support. You fucker is not the only one who lose your family, the man fucking lost his wife, while he couldn't help it since he had to support the family financially. You blocked him out, not giving him a chance for him to do his duty, caused him trouble, acted like a spoiled child who can only think for herself without even considering other people's feeling. Even upon hearing about your friend's issue, you just fucking ignore and blame all things to your father, right? Since it's the easiest thing to do. So good, much wow, a truly good friend here. Sorry guys, this chapter it's clear to see who's being the unreasonable one here. I'm glad the dad made up his mind and went to look for Koto, nevermind how wrong his relationship with her, abandoning someone in dire need is wrong. Miya, well, go fuck yourself with your newfound friend. It seems you had no problem at all being without your Dad for a night as far as I know.
Also, Koto's mom deserves it. Absolutely DISGUSTING. DISGUSTING HAS TO BOW BEFORE YOU.
