You were hanging out with Andry until one of your male colleagues approached you and you told him to wait. He glanced at you from far with jealousy look on his face toward your colleague. When you came back to him...

"I told you don't get any close with other men besides me. What if they steal you away from me!?"

he looks at you with a stern look on his face. We can tell he's clearly jealous and worried if you have any feelings toward other guys..his obsession is not healthy..
