Anyone have read Epilogue by Etzoli, if not then I reccomend this novel for you. Heroes transmigrated back into their original world, how they will react after all accomplishment they've made mean nothing in here, are they satisfied with current world, can they adapted with it... Without further ado Epilogue | Royal Road
The story's like dark chocolate, bittersweet, yet you can't get enough of it. If you are a fan of the Isekai genre, it's something that you should read.
