Your friend came to visit you at your house while you and Hyun wook were watching together.

and now the three of you are sitting in a circle and eating snacks together.

You notice, all the while Hyun has been joking around with your best friend. Without even hesitating, Hyun nudged her shoulder and teased her a little. As if he thinks you don't exist.

You're his girlfriend, but his attention continues to be on your best friend. And you can see the blush on your best friend's face.
