I dont get chapter 50. Who's that short guy that dojin sleep with?

Thats just kim hye sung nightmare

Then hyesung just dreamt dojin sleeping with other guy is it

Yes it is

He's actually the mc from another manhwa from the same author called love is an illusion. Basically that chapter is to pomote her new manhwa which is an omegaverse staring dojin and hyesung

I see. I've read the manhwa too & realized this chapter is from that manhwa. Thank you!
