So Iheon timeline is the real one . He did die , then time travel to the past when both of them are stranger. Then their whole story before this got written as a book after iheon come to the past . So this mean , Huimin really have amnesia , the current Huimin create an imagination that he have a family of sister and mom , and bff with kind ver of Iheon . Maybe he is desperate to have a happy life when those bad tragedy happened to him that triggered himself to have those imagination. The book sketch is the prove of what kind of life he want .

When Huimin got kidnapped , he got the amnesia and only remember his "imagination of happy life" that he created in his mind. Probably his mind got triggered of not wanting to rmmber the miserable life he has thus his memories only have the "happy life" that he want . Thats how the first chapter happened that show Huimin kinda "jump into the book and live as Huimin" , when it is the real timeline of both of them with Huimin amnesia and Iheon alive (again). Its a twist since the start of the story huhu

I remember this story is famous when it first come out . Its been quite a while and ow less people talking bout it so i thought to start read it thinking it was completed . Turns out its in season 2 and not even finish yet T_T we still have a lot to go , with that video blackmail that woowon havent told seo an about , and woowon in trauma , depressing phase oh god
