First time that I'm invested in side characters love stories

I'm not done with the manga yet (just finished vol. 24, so no spoiler plsss) but I love this series so much! it's the first time I'm actually invested also in side characters love stories. I wish there would be a separate series about Chizuru and Ryu, and Ayane and her futute relationship.

Typically for any other manga i would skip whatever chapters that is not about the main characters but right now i'm sooo invested in Chizuru and Ryu awww
