That he knows they are in a story called silence, Huimin thought Iheon was not aware of him being inside a book, he thought his real life was the one where he lived by his drawings, the life he wanted to have and that transmigrated into silence, a book he read but now he knows Iheon is aware that he is a character of the book too, but Huimin thinks Iheon became aware after his first heat cycle, he still doesn't know Iheon has been aware since day 1.
Huimin assumed it was after his first heat cycle cause that's when he remembers Iheon started to show more care for him, he knew details of him that in the book he shouldn't have known yet, so he thinks that is the moment he read the book and became aware of being in silence.
Makes sense. Thank you
What does huimin mean by iheon find out everything after first heat cycle? I thought iheon knew everything since the moment he entered the world huimin drew right after they died in real world and then they went back to past, the moment where they met again at auction.
