I think the subae got transmitted into the world as well or vise versa, and the ml went to his wolrd.
I also think this is a story and not his third life like some people claim because I think if i was his third life or true life, I think he would remember more but also you can easily argue thats why he doesn't remember his other life not even his name.
They are disgustingly cute, literally felt like vomiting of the cuteness and I love every freaking minute!
If anyone is wondering the manhwa is on chp 103 for the novel!
Thanks for this!!!!
