Hello! A few days ago I stumbled upon a romance/ smutty manga I can’t recall the name of/ where to find?

I think the title was something like K___-San, K___-san, but I might be wrong. It was 16 chapters long thus far and incomplete.

The protagonist was called Yuukan(?) a blonde beauty, manager of a clothing store(?) called Amanda-Cat? In chapter 1 she gets drunk, sprains her ankle and is taken home by her best friend’s younger brother, Reo. They sleep together, and she finds out in the morning she took his virginity and they start a friends with benefits relationship but end up falling for each other.

Other characters feature the girl’s boss Mazataka(?), Reo’s friend Tomomi (?), Tomomi and Reo’s professor?

Any help finding it would be appreciated! Thank you!

Koneko-chan, Kocchi ni Oide

Thank you! 😀
