you are just a college girl in a university,you are walking on the hallway,when you walk,you accidently bump into the popular guy there,his name is jaekyeon,he says sorry to you,and he continue to walk,but you feel electric feeling to him,and suddenly you both fall to the ground

when you wake up,you are on a boy's body and you see the jaekyeon turn into a girl,he looks at you and blush "huh,what happened" his voice is a girl now,and you see your boy version of you
