Heyy does anyone know what I'm talking about?? The only thing I like remember from it was that it was a bl and I think it was sub/Dom?? Or something like that, the only part I really remember is that when the sun said the safe word the Dom went into like a state(?) and was like worried. Then like flashback I think to when sub was talking about someone saying when you say safe word the Dom will feel like they did something wrong and hi into a state of worry. Something like that...

From what I remember it was a kinda kinky one the MC and ML had like stones that connected them together and the ML could enter into the MCs dreams or dream like world?? I only really remember the ending where I think of of the ML ex's took a stone and brought them both into a dream world and like tried to do something to the ML or MC but then MC realizes it's also his dream something like that and breaks free saves ML then other stuff happens, then they teleport somewhere naked with the stones.
