I reread this again and my feelings for that btch is still the same. I really mever hated ...

I was about to say the same! She deserves way worse for ruining a family and I also don't like how the father seemingly feels no guilt after cheating. Even though Shirotani feels awkward and traumatized by it, I hope he finds the courage to confront his dad about it. Cuz it seems like that whole cheating thing was brushed past even though it was so traumatic for Shirotani and triggered his condition? I'd be soooo pissed if I were in his shoes
