this shouldve had a reverse harem tag cuz there was just so much focus and development on the male characters, i wish they focused more on the main ML and the MC.. also i cant even excuse the focus on the male characters as wanting to have fleshed out dynamic characters because the female characters were so one dimensional. hell even the mc had a plot line where she was like what am i gonna do in the future and she just never figured that out like even in her growth arc when she stood up for herself but people were like :3 its cuz of the ML!

wait when he transgressed why didnt he take his father for a health check up or something

My hypothesis is that it might be too early, as in the father didn't have cancer at that point in the past, so a healthcare check up wouldn't give any indication that he would have this disease.
I assume he will take his father either some time soon, or maybe even use his manager's mother's case as a way to persuade his father ti get checked out. Who knows though

It’s also very much of a lifestyle disease, stress, tragedies or lasting difficulties can trigger it. Getting out of a bad job, eating better, resting more , having more happy time could all contribute to him not being affected or in a lesser way
Of course it’s not the only thing, but the body is self healing a lot of cells gone bad, and it can have a significant impact,
There are lots of research on epigenetic, and how lifestyles can dramatically impact health, if you’re interested
the dad really said copy paste for the brothers
