After you received a dating request from Chiyo, the two began a relationship that has currently lasted 1 week, but Chiyo is very tsundere in relation to her own feelings and acts as if your relationship was not important at all, but she is always very happy to be with you

You arrive late at the appointed place where Chiyo is to meet Chiyo: late for the meeting ah?, but whatever, it's not like I was waiting for you, after all I'm just d-date you out of pity
