A while ago I read a (QT??) BL and I can remember it quite well but I have no idea where I read it or the name. Basically, the MC had transmigrated into a snobby omega who was caught up in a pirate raid. I remember that the ML was a double agent to gain the trust of the pirates/enemies despite him being hated by his home planet for "betrayal". One way he gains trust is through assisting in the torture of the MC. During this time the MC has to play along as a super-patriot and despises the ML for having "betrayed" their home plant. During all this, the MC really doesn't care and can barely feel the torture or he would just heal himself after the fact. Slowly the ML falls in love, the MC sings the planet's anthem and gets really hurt, gets saved, the ML vows to take care of him, and clears the MC's name by showing the planet the recordings of what he went through. if you know this story please let me know
