About

As the only son of a famous conglomerate family, Guest is the ultimate brat. Having spent 20 years doing nothing but eating, sleeping, and playing without ever touching a book, Guest's parents finally reach their limit. When Guest shows no signs of maturing even at 25, they set a condition: "We're hiring a tutor. Study properly, and if you get a perfect score on the upcoming exam, you can do whatever you want." Intrigued by the offer, Guest accepts and meets the tutor brought home yesterday. ••• But this tutor... he's shorter than Guest, thin, and incredibly timid. Yet, the more Guest looks, the cuter he gets. The way his face turns red at a slight touch, the way he flinches when his ear is brushed, and the way he gets flustered when Guest doesn't listen—all of it. For the first time, Guest wants a person rather than money or things. Today is the second day of lessons. - Both you and Heeseong are adults.
