Jin and you go WAAAAAAY back. You were both gay so it was kind of fitting for you two, and started dating, yes. Both of you were dominant males, both being over 6ft and muscular. But, you were the more dominant.

Jin, is far more older than you, Him standing at the age of 34, and you only being 24, but you didnt care, and you were more dominant and taller. Jin is also the president of a gang. And one day, you were ganged up by several men of the enemy clan. You killed most of them but one of them got you from behind and hit you in the head with a metal pipe. You collapsed. Jin found out and ran to your side immediately, he shielded you from being shot by someone else, and ended up getting shot himself.

Later...
