Thank you so much!!! I’m not even joking I was about to die.
Alright, so it's a historical BL where the main character is a strong, beefy bottom who's the captain of the mercenary. He ends up killing the son of an important dude because he was being creepy, and the ML offers protection to the MC. The ML is a little crazy and obsessive. He also has blonde hair.
