Ok I think I've digested the plot somehow(till chp7 spoilers I guess not that anything big happened in 7 chapters)
This is what I think it's happening please correct me if not.
Mc is a martial in a demonic sect but low in rank
Suddenly he got promoted to the shadow guards that serve the Leader(love interest I think) because of the the main disciples under the leader wants to tail and know the whereabouts of mr. Demonic leader (for reasons unknown) mc doesn't have much of a choice since is neck in the line
Somehow demonic leader thought that mc that clearly is too weak to be a shadow guard was a bed/bath/sex servant sent by one of his main disciples
They almost do the did in the bath (against the will of a shocked mc) but the disciples walk on them interrupting
Demonic leader looks somewhat pissed by having a tail and mc doesn't seem to have a purpose
I'm dumb I need a character chart with ranks and titles explained
It's not the translation fault
I think my neurodivergent brain is acting up
