omg i love gekkan shoujo and chiyo so much... yes.... A SHOUJO GIRL AFTER MAKOTO'S OWN HEART and I love the idea of co-workers aka chiyo cutting in right before Makoto almost strangles a customer with a bouquet ribbon. Not that Makoto will do that... often, of course?? She'll at least be immediately shame-faced as soon as Chiyo intervenes.

They could be acquaintances at first and slowly become great friends because all Makoto wants in this au life is to be friends with a cute girl like Chiyo help

(IF I DO i'd still love chiyo cr... let souji gently bully chiyo and get killed by all her friends)
