Lee Jae In is a spoiled chaebol (Nothing new here). He spends most of his time yelling at his employees and royally ignoring his own grandfather (Eh, nothing new either here).

I feel the pain of Jae In’s employees.
Funny thing is this could be hard to believe for those who don’t know him as Jae In can show a kind side… but only if you are a customer of his high class hotel. As ruthless as he can be, Jae In is smart enough to make sure hotel guests are satisfied.
His life experiences a turn (probably for the best) when his grandfather decides to hand his inheritance to Kim Da Hyun, a warm school teacher. Da Hyun took care of the grandfather when she found him unconscious while outdoor with her students. From taking the grandfather to the hospital and paying his hospital fees, Da Hyun pretty much wins the grandfather’s heart.
