He's not acting like Miyoshi doesn't know about his dress-up habits, he's concerned 'cause he quit his last job 'cause he decided that he only wanted Miyoshi to see him like that.
Miyoshi satisfies both of Usaka's needs to not only dress cutesy and be accepted for it but also still love him outside of the cute outfits. There's no need to put himself out there for the attention he craves when Miyoshi gives him all he needs and more.
He's also concerned 'cause they both agreed Usaka wouldn't dress like that for work anymore. It already put Usaka in danger once at his previous job.
I dont know why hes worried when he literally did that before n even worse being intimate with male customers
