Its a big sum on its own but not when broken down in terms of a salary in Seoul, like they said thats 80k a year which is typical for a mid level corporate job anyway and with living expenses he wouldn't have much leftover at all, he only has that amount since he didnt spend it since he did multiple extra jobs to survive, so in terms of getting paid to be the rut partner of a chaebol its peanuts
Exactly! While it's a good sum to start your life, it's NOT a good sum at all for sleeping with a chaebol. Even if you factor in the costs that was used to treat the Aunt, It's definitely not in the millions. Bro should have leveraged for at least $1 million dollars. At least then he could put it into the fictional equivalent of the SP500 and get an average return of 10% or put it into a HYSA and get 3-5% and live off the interests. He could even travel carefree off that interests. And if I remember, bro only gets paid 10mil won or $6k-8k per time he sleeps with the Chaebol alpha. I'm crashing out bad man. $10k-15k would be the minimum starting rate man.
And anyone who thinks these are too large of a sum, just know there is a Chinese influencer who bagged millions by giving birth to a Billionaire Heir. They aren't even married (and her son is his only heir). And bro didnt even want the son at first.
So honestly, sorry for the crash out but bro should have gotten WAY MORE.

500,000,000 million won is only around $320,000-350,000 USD. 4 years worth is about $80,000/yearly. So like bro was NOT being paid very good for the trauma and mental health/physical health issues he received.
