This was my first ever watched K-Drama back then. It's a drama with mysteries in it. With every episode the mystery gets revealed a bit. It's a good drama. I loved Suho, his looks are just amazing as always. Due to Suho, I came to know about EXO band and then much more about K-Dramas and K-Pop. Overall it's a good drama that encourages you to get up even when you fall down. I loved the characters. Lee Yoo Chan is a serious look guy who just knows how to program all the time. And Kim Bo Ra is a girl who is full of happiness even though in her bad times. Even though she is suffering financially she always keeps her hope up to make everything workout.
At first it is just a guy who is into programming only. Later due to the girl Kim Bo Ra who is the cause with mysteries enters his life and he starts to change. His prosopagnosia get cured just for her at first. But, later it gets over as he starts to know people when he is left with nothing to do. Since, he has to leave his ceo post in NextIn company. But overall, it's a good drama which i have watched for more than one time and didn't get bored. I have seen suggestions that while watching K-drama for the first time you should start with Boys Over Flowers. But it was not bad at all to start with Rich Man though. It sure made my interest grow for K-Drama world.
