I kinda had the same thoughts but it doesn’t make sense. I’m lost - but here for it!
Want to know the spoiler if he is or not?
Noooo don’t spoil! (Thank you tho) apparently I’d rather slowly kill myself over learning the long way
I WANNA KNOW PLEASE SPOIL ME I cant take this confusion
Okay I'll just make the reply long to anyone who doesn't want spoiler
Yes, it's his sister from the previous life. He knows all along they're inside the novel but never said anything to mc which is messed up to me bcs he (use 'he' bcs he's a guy now) saw himself how mc has mental breakdown several times.
