sephiroth tries to maintain his aloof demeanor when he sees someone flirting with you, but inside he's seething, wishing hell on the man boldly trying to make you like him.

he analyzes him carefully, search for his strengths and weakness before he makes a move.

when he appears by your side, he places a possessive hand on your waist, tugging you closer, staring the man down as you introduce the two. after, he shakes his hand, making sure his grip is tight. it’s overly satisfying when he winces.
