Kyungsoo met Ran yi during her brother Kris's celebration party when he and his team-mates won a famous basketball tournament that was battled between their school and another famous school. Both of them cliqued together and became like two peas in a pod ; never wanted to seperate from each other. Months later, they slowly start developing special feelings for each other. They confessed to each other eventually and they became stronger because they were finally together.

'' No regrets in falling in love with you, my love.''

'' Shut up Soo, you sound like a weirdo.''

But when Kyungsoo's childhood female best friend who moved to America years ago comes back to meet the doe-eyed boy, Ran yi and Kyungsoo's relationship starts to fade away slowly.

'' What happened to those times where we were like friends with benefits?''

'' I'm sorry, but our friendship and relationship is done.''

Heartbroken, tears rolling down her cheeks as she runs away from the latter. As she runs across the road, she hears the '' used-to-be'' love of her life yelling from behind before hearing loud noises and everything turned black.

And that was the end of Wu Ran Yi's life

who passed away from a car accident on that day.

Kyungsoo cried, some of Kris and Ran yi's friends whined in sadness as they cried along then Kris beated up Kyungsoo,

Was this the tragic end?

Oh hell no.
 

'' W-why do you want to bring me back to earth? Am I going to meet my brother?''

'' Wu Ran Yi, you are now officially A Guardian Angel. And you, are to protect twelve boys. Kim Jongdae, Lee Min Seok, Xi Lu Han, Park Chanyeol, Kim Jongin, Hwang Zitao-''

'' Wait why must I protect so much boys like I don't have twelve pairs of hands you know-''

'' Oh Sehun, Zhang Yi xing Also Known As Lay, Kim Joonmyeon, Byun Baekhyun, Wu Yi fan also known as Kris-''

'' MY BROTHER? SERIOUSLY-''

'' And DO Kyungsoo.''
 

'' Oh what did you just say? Uh.. Jo koongsu?"
