So I just saw that it having pretty much mistypo:
4 month later at MLs wedding FL jump down from a rock and comit suicide. Ray is the one who found her and sience he feelt guilty for the whole situation: at the ball he left b*tch alone so she have the chance drug ML, and he couldn't even make happy FL, he used the time rewind magic, and until he using it he thinking about how much pain was FL when he jump down so the pain what now he feeling is nothing. After he wake up when he is 7 years old so sooner that FL.
The novel is much more different, I think they didn't want the suicide in the story.... In first TL he didn't know because the friend turned back the time right away, but in second TL he got kniw, the friend told him everything, he crying, broke down, because he caused the two most important persons death.
Spoilee from the novel.
In first TL the b*tch drugged ML and raped him. After ML decided that he cannot make FL happy anymore and he want to responsible for b*tch (IDK why he was raped) he broke off the marriage, and decided to marry b*tch. When this happened Ray (his friend) questioned him, and at last he could get out from him whats happened, but ML forbid to tell anybody. ML wanted Ray to marry FL in his stead, but FL was in terrible state and she didn’t want to marry with him. So friend began search how to make FL happy in another way, and found this time rewind technick, but the user would die so he put aside a bit. 4 mknth later at MLs wedsing FL jumo sown from a rock and comit suicide. Ray is the one who found and sience he feelt guilty for the whole situation: at the ball he left b*tch alone so she have the chance drug ML, and he couldnt even make happy FL, he used the time rewind magic, ans until hw usws it he thi king about how much pain was FL when he jump down. After he wake up when he is 7 years old so sooner that FL.
