*Only the first volume of the novel is adapted to a manhwa.*

##### Note:  
##### •Before the launch of S2, the artist had to redraw all of S1 art due to Korean complaints about Woo-yeon's appearance. Many overseas fans expressed their disappointment as Woo-yeon's tan skintone was lightened and his masculine features were gone.  
##### •On May 4, 2023, Korean audiences' complaints about Woo-yeon's "size" in CH.59 caused the artist to revise the episode to be erect, despite their previously following the "size"'s description canonically stated in the novel that Woo-yeon was portrayed as flaccid in that scene.   
##### •Starting at S2, the English and T. Chinese versions are uncensored.    
##### •Lezhin US and Manta have different English translations.

"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...
