So my theory is - this is real life. Whatever happened in the "book" has actually happened in their past lives where Iheon treated Huimin like shiit. Huimin's dream...that he apparently forgot while he woke up. The one where he killed himself after Iheon died protecting him. Didn't he say something like "let's meet in our next lives and love each other and have a happy ending" or whatever, right before he sh0t himself?
So what if the new reincarnated Huimin thinks he's a normal human being with a mom and sisters and a best friend named Iheon, and has somehow isekai-ed into an omegaverse book he read about the main characters having the same names as him and his friend, has his memories from his past life but thinks it's a story of a book, and now the hospital sessions and the dreams are making him remember his actual past life? Meanwhile during the start of the manhwa, reincarnated Iheon didn't have his past life memories (had his hair up) but somehow in the middle he regained all of his memories (kept his hair down) and remembers why and how much he had hurt Huimin so he tried to be soft (successfully) to Huimin and loved him and doesn't want Huimin to regain his past life memories because of the ✨trauma inflicted by yours truly✨
