In exchange to fulfill his desperate need for revenge Luhan decides to make a binding contract that forfeits his soul to Sehun, a demon from the depths of Hell, in order to bring pain and misery upon those who have wronged him horribly.

Stumbling upon a heavenly being was something Sehun never expected to do but stumbling upon Luhan, an Angel that couldn’t fly, was something entirely unbelievable.

Sehun and Luhan, their bonds that lasts forever through every alternate universe, lifetime, and love.

Sehun has been involved in the mafia for so long that he's practically bored with it. Day in, day out, same old, same old, whatever. That's not good. Sehun is young and reckless, he joined the mafia for the thrill, he dislikes being bored so he's going to find something to entertain himself and the new recruit, Luhan, seems oh so tempting. But soon enough Sehun is going to learn that he's not as bulletproof as he claims to be, especially when no matter where Luhan seems to aim his target alwa

Sehun's fangs have finally begun to emerge, however his newly forming fangs are aching so badly that he actually needs teething toys to dull the soreness but when those don't seem to be enough, Luhan just might be willing to become Sehun's personal teething toy to save his mate from his fang pains. 

Dandelions are known to grant wishes if you pluck them and blow all of their seeds off in one breath. Sehun just happened to pluck the wrong one. It was apparently one of a kind, the only one in existence, a rare sub-species of dandelion that was called Luhan and it was not happy to be plucked.

Sehun had eleven different bets he could have made but he never had much luck with bets in the first place. Now, he's stuck playing this messed up game of roulette.

Luhan is one of the top performers in the circus while Sehun is only his apprentice that's really clumsy but maybe Luhan caught some of Sehun’s clumsiness because the two end up falling for each other even with the safety net to catch them.

Sehun is a Nalgae, a guardian of happiness with wings and special powers included, although he clearly doesn’t act like one he takes his job pretty seriously especially when Luhan, his closest friend and not to mention a normal human, manages to find out his secret and proceed to accidentally bind the two of them together in an eternal link that can’t be broken. No wonder this ended in a weird fall for the both of them despite the wings included.
