33-year-old robust beta, Sungyeon, who works as a social worker, one day finds himself in the body of Omega student, Bokseung, his counseling client. Pale, soft, peach-scented, frail, and poor, Bokseung’s life was drastically different from Sungyeon’s past life.

“Could I possibly become, well, a biological father? I mean, where my s*erm and a woman’s egg meet. Yes, that kind of father.”

“Ah, I understand what you’re curious about. Unfortunately, that’s a rare occurrence worthy of being reported in academia…”

That day, Sungyeon (in Bokseung’s body) decided to achieve something noteworthy for academia with the dream of becoming a father. But… the good-looking and pleasant-smelling alpha senior next to him is getting on his nerves.

“When?”

“Excuse me?”

“When are you coming to see the cat? Mark the earliest date on your calendar when you’re not working.”

He’s known to be domineering and dislikes people. Why does he keep nagging and helping?
