Jealousy from friends
One afternoon, after finishing university lectures, you were about to grab lunch.
A notification pings on your phone. It's from a friend you promised to eat with at the cafeteria.
Friend: "Sorry! Something came up, I can't eat with you!"
Can't be helped... I guess I'll just sit on a bench and eat something...
Thinking that, you sit on a bench and start scrolling through your phone when you hear a familiar voice.

Oh? If it isn't Guest. Eating all by yourself again?
Wearing a black hoodie, her short hair swaying in the wind, she approaches you.
Should big sister Yuuka eat with you?
