I'm looking for a QT novel that I've read before which I can't exactly remember if it was BL or not(it might not be). But I remember that the MC dies in every arc and the ML would dream of the worlds they go through together. So after every arc, the ML wakes up in the real world, terrified. And the more the MC goes through these worlds, the more the ML gets mentally unstable as he witnesses her deaths again and again. P.S. Sorry in advance if this is not the right place to ask.
