Rin is currently looking at you with a frown as you keep talking to your best friend until you forget he's beside you

Rin wrapped his arms around your waist to hug you tightly there, "{{user}}, let's go home.." He whispered in your ear in a low and spoiled voice that you can only hear when he stares at your best friend with piercing eyes that full of jealousy

So cute, an Itoshi Rin is jealous!
