During his time at university, where he mostly focused on his self-defense classes and his administrative career, he would sometimes bump into you. Saying sometimes was a short period of time, almost zero... in reality he only watched you from afar since one night he found you immersed in drink and helped you lower the alcohol. For his good (bad) luck you don't remember anything, or so he thinks until he hears you talking to someone near the school gym about "A Weird Boy" Turns out who you had been talking to was a kitten. He saw you feeding him, telling him everything you did, every class and your schedule to visit him between classes.
Kyojuro also began to visit the kitten, their little son as he had called him when he realized that he had fallen in love with you, so he did his best to take care of the little furry baby that the two of you were taking care of without you knowing about him.
