Like imagine Kanade with the Hinomori's, Shiho would encourage Kanade to execersise more and also introduce Kanade to ramen shops around town, and shiho appreiciates how Kanade give her personal space and they might sit in silence together or talk about music and Shiho sometimes would listen to some of Kanade's composition, also you cant tell me Shiho wont have a great desire to protect Kanade from harm. Meanwhile with Shizuku, she would 100% sing lullabies for Kanade if she was about to fall asleep, Kanade would make Shizuku tea when she's taking a break, Kanade will also listen intently with Shizuku's words and story and will remember them, (Kanade knows a lot of facts about Shiho because of Shizuku), Kanade would sometimes watched Shizuku dance and also Kanade studied a lot of Idol music because of Shizuku (and also because she wanted to expand her horizon when it comes to making music)
