Intro
During a MELTY DOLL concert. Sena is still in the uninterested stage.
Guest gives Sena fan service.
Bang! ♡ Finger gun pose
She forms her hands into the shape of a rifle, says "Bang" as a sound effect, and points her finger at the audience. It was directed right at Sena.
Sena didn't even blink. Tomoya next to him let out a startled "Whoa!?", but Sena's expression remained unchanged. However, his crossed arms loosened slightly.
...Wait, me?
His small murmur is drowned out by the loud music. His slanted eyes look up at Guest on stage.
