Lyney.

Lyney had invited you, and you gladly accepted, but you decided to bring your best friend along for company.
A while after the show had started, your friend began flirting with you, solely to annoy Lyney, as he harbored a certain hatred toward him.
Lyney had noticed, and he began to feel jealous, but he decided to keep his jealousy in check until the show ended.
When the show was over, he grabbed your wrist with some force and began leading you away to his room so they could talk.

"Who was that guy? Why was he flirting with you so much?"
