Forgotten title

[Nagtatago]

Im trying to remember a manga about a 30 year old female mangaka who made a manga with the harem stereotypes despite hating the genre itself. I think it's seinen. But I guess the whole point of that manga was the love triangle between her and her 20 year old assistant (whom she calls 'assasin') and a 40 year old guy who seems to be the director of the anime that will be based on her manga

I enjoyed it very much but lost track so ofcourse your help would be very much appreciated
Thankkkiieees

Hello, I don't know if you've found it already, but I think this must be the manga you're talking about.
