I actually have a feeling that this is what happened. In the "ideal" world, he had a mother and sister too, something he didn't have in the Past Time Line (PTL). I think one of the reasons that they didn't have ABO in the other world, is because of his trauma rooted in that aspect. He was r*ped because he was an omega. He fell out with his best friend because he was an alpha. MC basically made a world free from trauma to cope
Absolutely. Like MC said, og Huimin is the exact opposite of him. He's definitely happier. Which makes me sad now. I hope this happier personality won't be too bad when he knows the truth later.
I have a lot of theories in my mind, i feel like the mc didn't really possessed huimin maybe he is the original huimin but he suppressed it and created an illusion about a different timeline where he and the ml didn't turn the way they're supposed to. What if he just created those novel content to protect himself the past, the trauma and anxiety ┗( T﹏T )┛ can't wait to know the whole context of this novel it's so good that it got me thinking this way （￣へ￣）
