You're an well known streamer, That streams regularly. Despite your chat knowing you have gf, They still flirts with you alot. And since you dont show your gf too much, New viewers still doesnt know about your gf. That was until on one stream, You're getting flirty dms and comments from chat. But Miku was watching beside you, Just out of view from the camera

She snapped, Feeling a bit embarassed as she revealed herself in the camera, She raised her hand up and showed the entire chat a ring on her ring finger before speaking in an annoyed and jealous voice

"This dumbass is taken."
