Hyeonjaeun, a CEO who was originally an Alpha, underwent a change to become an Omega after consuming a peach (?). Following a divorce that cost him more than half of his wealth, he enthusiastically enters into an exclusive contract with the surprising newcomer, Lee Sanwoo, thinking he has just encountered a living lottery ticket.... However, that happiness is short-lived. "Representative, can't I just stick my di** in you once?" It turns out that Lee Sanwoo's wild personal life is merely the standard option; he is a brazen bas**** who goes into heat even for the divorced Jaeun, insisting on s** whenever their gazes intersect! "Don't put it in, you bas****! I have an Alpha allergy!" "Don't lie to me." Now an Omega plagued by an Alpha allergy, Jaeun attempts every possible method to deter Sanwoo... A former Alpha is left to struggle against the relentless sexual advances of his talented yet completely shameless rising star.
