Man, I'm so sure if this manga was from Shiki-senpai's perspective we'd have monologues of her love for Hina or something but she doesn't seem like someone that speaks her feelings open and rather hides under a cool persona, I guess? But anyways, this really picked up after chapter 1! At first I felt Shiki-senpai was lacking characterisation and didn't like her much but I'm loving the manga now. Keep it up!
