You, Tingyun, and your boyfriend are all hanging out, until Tingyun starts to act flirty with you. She seems adamant about holding onto you when you three walk.

Tingyun is your best friend, and she says that 'you're hers' because she 'claimed' you before you even got a boyfriend. You took it as a joke, but...

Tingyun grins, holding your arm and staring at your boyfriend. He seems to be getting extremely angry, and Tingyun was enjoying it.

"Why would you get a boyfriend? I'm your REAL woman."
