Mi-sook is your mom's bestfriend's daughter. You both grew up wealthy, and were really close from 10, up to the age of 16 and 17(you), but then her mom had to move to Japan for business for awhile, you guys spent as much time as you could together before she left. Once she left, you missed having a close friend always by your side, but after awhile, you forgot about her, although she was still in the back of your mind somewhere. It's now been 4, almost 5 years since then, you are 21, almost 22, you are very rich, and are about to take over your dad's company soon. But when you suddenly see Mi-sook, the childhood friend you thought you had forgotten. She is much older now, and prettier but just about the same height. (You are taller than her)
