I dunno why i cannot reply to the first question but what I'm saying is all true because i read the novel
I treasure hunt and found a treasure because thats the only site where you can read the story and sadly i check it again but the site is already down
Ps: the translation was sucks though especially the name. As far as i remember, the chairman name was about food. Or am i just hungry(〜 ̄△ ̄)〜

I think they cut about his achievements where lots of hospital wants him
They offer him like million of salary
That achievement was like written in the history because he made something like medicine
Then this conference where the chairman got mad because he wasn't expecting that doctor kim was the one who made that medicine
Then doctor kim made a promise to himself that he would take a revenge. Hard way. Then the chairman son says that wherenever doctor kim is.. he is till out of his league

About his ex wife. Isn't she a bit unfaithful? i mean. In the worst situation she left her partner, I know she was suffering. But like with doctor kim, she just left like she was the only person suffering. Not giving a chance to dr. Kim explain his side of story and resolve it together. That's just my opinion
!!!VERY BIG SPOILER SO DON'T READ THIS IF YOU DON'T WANT A SPOILER!!!

Thanks to the bastard chairman wanting to sent the grandfather to US
Doctor kim save his girlfriend grandfather
His girlfriend grandfather was about to die but doctor kim save him then
The grandfather ask doctor kim what does he want as a payback
But doctor kim refuse and tell him to wait
After 2 years(??) He meet his gf grandfather with his gf and ask her hand for marriage
I forgot the arrangement but doctor kim made something that made the chairman mad because it was internationally recognized
Then after that(forgot the detail)
The chairman got jail and doctor kim and his gf got marry.(PS: the mafia and the other blonde girl that's friend of mafia got turn down by doctor kim because he really love his gf)
His exwife got together with the chairman son(i feel bad for this girl because at the matter of fact, she did nothing wrong yet her life is messy) and in the end got divorce. The chairman son have mental issue so he is on psychiatric care.
After that, doctor kim forgive the chairman son.
The ending was he has a son who want to save people just like his parent.
Very satisfying ending.( ̄∇ ̄")
