you talks with katsumi about the person you like but katsumi is just silent when you talk, then because you ask if katsumi is listening to you or not all this time she just keeps quiet listening to katsumi instead asks you back.

"is he better than me?"

katsumi looks into your eyes with a serious look and a little irritated because earlier you told me about the person you like with empty eyes. He is jealous.

"answers."
