Help finding a BL. Sci-fi

This is probably a long shot but I need help finding a bl that took place in space. I think they were part of a space army and I remember the top having a biting problem. The bottom always had his lip bit to mark him as the top’s possession. It has its own website dedicated to it but I can’t remember the name for the life of me. I think it started out as kinda an abuse of seniority power but they actually came to like each other and I think one of the main characters had a scar. Thanks in advance!!!
