Hello! I'm sure that there are a handful of bl novels with this concept but at the moment I can't really find anything. Looking for BL novels where the MC dies but then wakes up to find he has gone back in time and the ML(s) also come back as well with all their memories from before they came back. The ML(s) feels remorse over his death and begins to pursue the MC. (I would really appreciate it if there is a scene describing how the ML(s) felt after the MC died.) Thank you!
This one is quite similar to what you're looking for but the MC doesn't go back in time, but his exes and friends are the ones who get reincarnated and they all tried to get back with him After I Got Married, Those Who Betrayed Me Were Reborn
The Cannon Fodder Strikes Back - MC returns with all his memories; ML doesn't remember at first, but his memories come back in dreams later. ML has a white moonlight he "loved," and MC was his cover- only at the moment of death did MC find out. Of course, ML actually had feelings for MC and dearly regrets. Yes there is a scene of MC's funeral in ML's "memories."
