Love me! [illumi X Oc]

"He's a cold, heartless, assassin who takes pride in his job, he's truly evil. A man who walks around bearing no emotion." That's what anybody close enough to know about Illumi always say about him.
His cold gaze has always driven people away, they always pushed him to the side and never gave him a second look. People always scurried away the second he laid eyes on them.
Illumi never paid any mind to this, he stopped caring at a young age.
Arisu found Illumi quite peculiar but she never saw him less than a human. She even managed to get herself wrapped around his grip.
