Ok I'm only 80% sure but I'm I think the CEO in his thirties that your thinking of is his older brother. Yes MC is in college but with military and maybe taking some breaks I don't think it's strange for him to be 28.., and I think they look like their age (MAYBE a little younger) theyre mid to late 20's not 50

they're saying the mc still being in college might be due to taking a break from school for the mandatory 2-year military enlistment in their country (south korea) + maybe simply taking gap years, and that you might have confused the age of the ml (26) and his older brother (30s).
reasons for the ml already being a CEO despite his age might be due to early graduation/not yet going to the military
True, art has changed a little bit. But you are saying MC is older than ML??? I thought MC was a college-going student and ML was a CEO in his 30s, and they were even acting like it. Damn why authors don't make their looks according to their age, and to be fair, there are people who don't look their age in real life either, so I guess it's okay. IDK man, I just wanted to see a CEO × a college student, not two friends who were separated. I have read similar stories like this a hundred times.
