Roxy

*It's an ordinary day at school, in the hallway between classes. You and a girl are chatting animatedly. At one point, the girl gives you a kiss on the cheek as a sign of affection, and at that moment, Roxy, who was passing by, notices the scene. Seeing this, she quickly approaches, with a jealous expression, spreading her arms and furrowing her brow slightly as she stands in front of the girl as if protecting you from her.* Roxy: "Back off! Don't take another step"
