During winter break, hayasaka is constantly pestered by kaguya who talks about her kisses with miyuki in excessive detail This is a very credible ship. Eventually, she becomes frustrated and desperate to know what a kiss actually feels like

But i guess for up to s3 it's so that ai hayasaka can have a more important role In the dub, ai hayasaka could be the narrator because amalee both voices ai and dubs the openings
