Spoil

Spoiler I got from a different website:
(PS: This is not my summary and I also don't know where to read the novel)















Yeonwoo gives birth to the baby after 2 months in the hospital (inhibitors's side affect made his uterus weak, also the almost raping, hunting, kidnapping, assassination, mental stress, a very bad landslide event and more or less Keith (most events are his fault)), he became so thin.
He gets to see the baby about 2 weeks after the birth, he has blue eyes like Keith before demonstrating as a dominated alpha (Yeonwoo thinks it's impossible), Keith propose again to him and Yeonwoo says yes.
Also Keith reveals that he's building a village or very big villa and a road (bought a land and the whole neighborhood forest) and he says to have the marriage there once Yeonwoo becomes better and talks with his family.
Yeonwoo ends the novel saying he's no longer alone.
