Jung Yunho is a normal 18 year-old student.. or so it seems. But for him he's nothing like the other normal boys his age because unlike the rest, he retained his memories from his past life, for what reason, he doesn't know. Not until he met again the girl he loved in the past.. but she was reincarnated as a boy, Kim Jaejoong. The prettiest guy in his class. How will he face Jaejoong, whose soul was of the girl he loved... and he killed?

Jung Yunho and Kim Jaejoong have known each other for almost eleven years and have been dating for nearly eight years. They love each other, no doubt. Enough to make Yunho ask Jaejoong to be his wife before their 8th anniversary. But instead of saying yes, Jaejoong gave Yunho a dare.. A dare that was bound to change their lives forever..
