"What kind of person do you think I am?”
"……a stranger."

Lee Soo-ha, who has been locked up in an unidentified facility for a long time, is dragged by strangers and meets a man one day.

Lee Soo-ha, then lives with that man, he found out that he is an Omega who was sold to him, an Alpha.
He is concerned about his situation where he has no heat cycle and is unable to conceive due to his abnormal physical condition, but that man doesn't care even though Lee Soo-ha is not doing his job as omega.

It's just confusing to learn what a man's inside is, the hatred towards him and the often feelings of deja vu, and it's just confusing as unknown things continue to happen...
