It seems that indeed the friend was an impetus for Hana having more spicy thoughts, that cream licking also really stayed with her.
Her Ex though ? So is it like i thought and Hina got really close to that girl as well which made her uncomfortable and thats why they fought ? Hina seemed to always have an idea of her liking girls and wasn't too surprised at her gay thoughts towards Hana so they started with Maiko?
I mean its not really forced drama since no drama happened but i guess Hina will coincidentally find the autograph ?
