That's a great point and appreciate you pointing out that Hirano presents as ace! I agree that HtK does not follow the trajectory of a standard romance which makes any progress between them feel so precious and special ٩(๑❛ᴗ❛๑)۶
I'm on the edge of my seat to see how Hirano continues to explore his feelings for Kagi and the extent to which they may/may not have physical intimacy

They are my Roman empire because the slow burn is BURNING y'all! I love them so much and how emotionally mature Hirano and Kagi-kun are with each new chapter. (≧∀≦)
