hhhhhhhh's Things

hello, i am desparately searching for a manga that i only have a vague memory of:
i think the seme was the ukes boss/manager/designer (someone in a higher position). The only scene i remembers is something like a book signing event where the uke was helping out and was acting friendly with other people and the seme gets jealous. I think the artstyle kinda reminded me of tennouji mios

any help would be greately appreciated
