What a train wreck but then what could you expect with such a cast with such backgrounds?
A father who was losing himself to his job to avoid confronting the realities of life and discussing why he may have flaked on his wife's deathbed. A daughter who blames her father for everything when she's shown to be immature/selfish and unwilling to speak with him about why he is the way he was while her mom was dying. A teenage girl with a very controlling mother I assume with "daddy issues" (never seen her father yet), most likely would try to latch onto the first "white knight" that she thought could help her escape from her situation. They all seem deserving of their fates.
My prediction of how it'll end? I don't know, but I can see the MC either going to jail or losing his job going the destitute route due to a damaged reputation. I can see his daughter ending in one bad relationship after another (the guy she's attracted to was smoking in school while skipping classes... she has a thing for "bad boys" which usually end in "bad ways") if they show it further down the line. The FMC, I see a bad end for her because I can see the MC's daughter exposing her to others in school about dating her father as a form of immature retaliation, which would give her the reputation of "sugar daddy thot" that does such things for money (it seems to be a common trope in many mangas which seems to green light the "she deserves to be raped because she's a loose girl anyway") and many, many, more bad things she's going to have to endure or suicide out. I don't see a good or happy ending for any of them, but the best I think they can get to the point they have some semblance of peace, licking each others wounds, and going their separate ways
