Is the sperm she used Yi yuns sperm?? Because i remember them talking about it being stolen... why didn’t she just use her husbands sperm???

It is Yi Yun's sperm I believe and I think because of the family's weird rules.
The successor is always the first son from the male line.
The successor doesn't come from the female line. Hence why she stole the sperm. If Jinyao becomes the successor then the child she has with is "Jinyao'" first son automatically makes the child the next successor after Jinyao
BUT
The Aunt said that the child is her brothers illegitimate son. So I might be wrong about this. Not sure what her plan is.

Ya’ll stop hating on Taejoo... put yourself in his shoes

Mans literally gulilted Taejoo into a relationship ofc it wouldn't last long.
He also doesn't even consider how Taejoo feels he only cared about himself and how he would get hurt but not see how much other people have suffered because of his selfish behaviour.
So he deserved that heartbreak that's karma for you.

But even if so he should have thought instead of being selfish. Like he for real told Yoon don’t talk to me anymore I want nothing to do with you immediately after him waking up. Think about Yoons mental state at the time dude like you were friends way before lovers. He could have made boundaries and have been there for him as a friend instead of pushing that on him and later clinging on him like a baby when Yoon didn’t stay head over heals for him. And even if not that at least had distance but still support. Good thing Yoon is strong bc Teajoo really could have set him to the edge by being that selfish.
He was sus from the start
