At the beginning of every week the students at Yunho’s school all compete to see who can write their name on one boy’s hand. The senior doesn’t understand the hype of writing his name on another person. After investigating, Yunho discovers that the boy, Kim Jaejoong, will date whoever writes their name on him first until the name fades. Once the name is gone, so is the person. At least, that’s how it has worked so far. The reasoning behind it all is for Kim Jaejoong to find the one he loves.
