Oh Sehun is a gone case when it comes to his relationships with the opposite . He is skeptical, cynical and doesn't think "love" should last more than a few days, just long enough to have fun and forget it.

On the other hand, Kim Suho is a newly attached young man and a lovesick puppy. He breathes love and world peace.

The constrast between the two was too huge for Wu Kris who likes to mess Sehun's life. The young chinese man dares him to break his strict rule for no other than his bestfriend, Serenity.

Now Sehun, the question is: do you better win or lose?

Kris suddenly spoke up, having a new idea to torment the younger, « What if it works out for Suho and Rin Ah? » At this, Sehun lift his head, a small smile on and his eyes twinkling with a new interest for the situation. « You want to bet, ge? » he asked, confident as ever. « Why not? » Kris challenged. « If it does last, you will have to date a girl more than three times » the chinese young man stated with a raised eyebrow. « When I win, you will have to give me your "bestfriend" 's number. You know, the girl you're so protective of » Sehun smirked knowing Kris would hate it. And sure enough, Kris's eyes widened a bit at this. He didn't really like the idea of his bestfriend being involved with Sehun... She wasn't the type of girl that would even try anything with him... Nor was she the kind of girls Sehun plays with... But Kris suddenly broke a smile and stuck his hand in Sehun's direction. « You're going to love it. I'm so winning this time, maknae »
