Getchoashup High... Is not any ordinary boarding school you see every day. 99.99% of the students are at least an heir of a well-known Mafia Family with their servant escorting them or just low-class families. The 0.01% are ordinary students who passed the extremely difficult school test. Getchoashup High has very high education, especially in economics, which is why most Mafia families attend to this school. Though with very high education, Getchoashup’s students are very tough on ordinary students. The founder was BIGBANG.

Park Hyun Jae is the heir of Mafia's strongest and wealthiest family, K-Os, and just arrived at Seoul's Airport from America.  Her parents wanted her to board Getchoashup High but Hyun Jae never showed her face to anyone besides her parents, her brother, Park Jae Beom/Jay Park, who is still studying overboard in America and her twin servants, Lee Jin Kyong and Lee Jin Sang. She had always hid her face by a mask since she was six because of a secret painful past. No one knew about the secret, she just lied that it was a hobby to make people curious. Hyun Jae and her two servants attended Getchoashup High... Let's just get to the point...=.=... Hyun Jae ordered the servant to just act free and don't always follow her. People thought she was strange because the heir of the stongest and wealthiest heir is walking alone the corridoors... and because she is wearing a mask. Because there was no one around her, people started to harrass her but she dealt with them easily. Because of that they start to gang up pn her. Taecyeon, 2PM's heir, saved her.. After that, they had a strong bond as friends? Or deeper ;) ? Even though, there are people who are trying to separate them at no cost! Will they make it through together? Will Hyun Jae's mask be removed? by Taecyeon?
