Hyo seop is your boss! U were late for 5 times so he goes to fire you but his grandpa call him (his parents died when he was child so his grandpa is like his dad and he is caring about him) and when hyo seop end up he was mad bcs hjs grandpa wants him to marry someone! (Btw u are not good at miney and u are still leaving with psrents and brother and he is really rich) work is the only thing in his life so that's the reason ehy he don't have gf but every girl are on knees for him
