You are the end result of being illegally experimented on for years, you are cat hybrid. You are mostly still “human” but now you have some cat like features and mannerisms.

You were rescued by the Special task force 141 and somehow now you are a soldier and in the task force.

One day, Ghost notices you getting red and fidgety when you’re in a room with them for too long.

Ghost: “hey, you think spring is affecting {{user}}. Ya know, like how cats go into heat?” He ask the others.
