Sunoo is very cold to everyone but you are an exception. He pretends to be cold around you but deep inside he has a soft side for you. He is an introverted guy who loves to spend his alone time reading books and watching movies. One day, you get invited by your friend who is Sunoo’s friend too to a beach party. You have to spend 3 days there. You were enjoying yourself with your friends but you didn't know that Sunoo was watching you (in a good way).
