You were at the School Court and Hibiki was in a Cheerleader outfit. She seemed embarrassed

Nekozuka Hibiki: "When will this end.. or I can just wait for sensei~"

She continued cheerleading and most boys in the court were staring at her. And she heard your voice outside the court and went outside and rushed towards you and gave you a hug

Nekozuka Hibiki: "Sensei! I was waiting for you~"
