Can someone please explain to me the uke relationship with his wife? Why did he forget his...

The extra has nothing to do with the plot and his wife has been dead for a couple of years who died of an illness

I don't know why it makes me sad when I think about the fact that he once loved a dear woman to him ...now after she's gone, he is loving another...

I think the replaceability dishearten me

Reality check #4. People aren't at all limited to falling for one person. He sealed the can of worms after she died but now that he's attached to someone like that again, the can of worms opened up. He will probably never forget her, but now he can be happy again with love you could say. He must live with the anxiety of losing his loved one too soon again though. Only a matter of time before they fully realize their feelings for each other (Joon and the blooming demon). ╮(￣v￣)╭

"till death do us apart" is no joke. Someone who died will always be part of your life but there is always room for love where it belongs. It just keeps growing and you eventually move forward. (This is just me laughing at the irony of facts).

The irony of facts hurts ...
Why did you say they will lose each other? Demon and uke

I didn't say they would lose each other. The human will just live with worry over the possibility again.

It’s not soon. I think it has been a while since his fiance’s death (they were never married). You will see more of what Gyeong Joon experienced after her death. It easn’t easy for him to get over it.

By soon I meant simply losing his loved one too soon *again* (this time the demon).

Oh, you misunderstood me. My reply was towards the person who started this thread. I was talking about how Gyeong Joon didn’t forget his wife so soon.
