Ha-jin Lee, who hides his real name ‘Yuhan’ and his past, lives as a ‘beta’.
It has become his daily routine to succumb to Jinseung, the son of J-Tech’s CEO, alone, without a family, and with debts.
One day, at a meeting place with a business partner, Ha-jin reunited with his first love from high school, Seong-hyeop.
Seonghyeop, the son and friend of the driver who had stayed at Hajin’s house in the past, became the CEO of a large corporation.
Even after 10 years, the two people still have each other’s pheromones clearly engraved on and in each other.
In the reversed relationship between the two, Seonghyeop proposes a sex partner to monopolize Ha-jin, who left him.
