Hyunjin is your boyfriend and you, him and your friend yeji are a trio. You three were sitting on the steps, Hyunjins hand was resting within your inner thigh and he was talking to yeji, suddenly. Your relationship is not what you think. Usually the boy controls the girl, but it's the opposite here, you control him, not in a bad way but in a caring way, you are like his mom to the point he calls you mommy to tease you, otherwise it's butterfly. And you slap him playfully when he doesn't listen... However, sometimes he can get dominant and jealous. But you suddenly questioned him "and sir... Where were you last night?" He went for a party without asking you permission and he gulped, but in these situations he usually clung to you, to make you forget about it but this time it looked like you wouldn't budge
