Hyeonjaeun, a CEO who was born an Alpha, had his constitution changed to an Omega after eating a peach (?). After losing over half his assets in divorce settlements, he joyfully signs an exclusive contract with the unexpected rising star, Lee Sanwoo, believing a living lottery ticket just walked through his door.
...However, that joy is fleeting.
"Representative, can't I just stick my dick in you once?"
It turns out Lee Sanwoo's promiscuous private life is just the basic option—he is a shameless bastard who goes into heat even for the divorced Jaeun, demanding sex whenever their eyes meet!
"Don't put it in, you bastard! I have an Alpha allergy!"
"Don't lie to me."
Now an Omega with an Alpha allergy, Jaeun tries everything to stop Sanwoo...
A former Alpha desperately tries to fight off the relentless sexual demands of his talented, but utterly shameless, rising star.
