The main character is in love with his childhood friend and so does he but he doesn't know. He finds a red book and that book contains what is supposed to be his friend's life where he is happy. Whenever he tries to go against it something bad happens.
The quality of some of the pages are bad but if you save them in your album it looks normal. I also reread some stories I read a year ago and the pages also turned shitty even though it wasn't like that before.
si (heejae) bare minimum enjoyer
