It started with pure intentions at first. Just a normal "boyfriend trying to visit his girlfriend" thing. But when Sehun starts to get the hots for his girlfriend's daddy, destiny bends itself. Luhan was a high school senior then and he didn't expect it to turn for the worse. But one shot of tequila and two parallel lines, and he says yes. He gets his peace until his daughter brings home a boy. His name is Oh Sehun.

Lucifer sends Sehun his favorite book and he needs a specimen to test if it works. How unlucky can Luhan be?  

What are they hearing? On the other side of the door... Taemin and Minho... Where the sounds from their room, real?!
