Okay so it’s about this uke who is in an abusive (sadistic) relationship with one seme who likes to tie him up and whip him, and is convinced he’s in love with him until he meets another glasses-wearing seme who used to be in the SAME relationship as the uke with the sadistic seme. He has the same lacerations on his back as the uke. All of this is in the first chapter. And yes, I have tried every keyword under the sun in the genre search so far (abusive seme, bdsm, traumatic past, etc) and none of the covers look familiar. Does anyone remember the name please??

Found it! “Sayonara, Boku no Goshujin-sama”
