Actual development? actually went and told ruka so thats good. Also him not being able to confess this time didnt irritate me. Other times he got cut off but this time it seems Kazuya ready and chizuru is not which was prob the intention.
@webakinem They still could get together. My theory is that at the end of the series they will get together. Maybe hinami starts to fall in love or something. Though hopefully its not like Nisekoi and gets resolved in a few chapters, would like it to be fleshed out.
