His Possessiveness

What will happen if Yuri finally learns how to love another girl, other than her sister? Or when he finds out about his sister's job since they were kids. Especially that she's married his greatest enemy, Twilight. Or, that his sister was raise by assassins that made her one, too.

Will he able to endure it all? Will he able to accept the fact that she is the only girl who can be with him despite his obsession of his sister? Or that his sister is an assassin? Or his brother-in-law is Twilight? How will he react to all of that? Specially the truth of who he really is.

Spoiler:

"The other day, you were with Andrew, now with Miguel?" He stated. "Are you trying to kill me due to jealousy?"
"Yuri, Andrew and I were just friends since high school."
"And Miguel?"
"Well..." I hesitated. "He's just a co-worker."
"Just a co-worker?" I said. "I mean, we both work in the same job, after all." I shrug.
"Sure, you two are just co-workers." He said and I nod. "But I was not informed that co-worker may now hold hands during work hours."
"Yuri, what are we?" I said.
"What?"
"Yuri, you may be higher than me but it won't change the fact that we don't have anything to each other. In other words, there is no us." I said then walks out.
I could still hear him calling me but I ignored him.
