Does anybody know this BL oneshot?

Its a one shot thats about this man that teleported to this place and he met this long red-haired guy. They fell in love and did the same thing over and over like a routine and the mc got so sick of it and wanted to leave. The red haired guy killed him because he didnt want the guy to leave him. And after he killed him, a new girl teleported there. And ig its like a cycle of him killing ppl that tried to leave him and a new person teleporting there. I think this oneshot was included in a collection.
