Mundanefan's manga / #Doujinshi-mangaka(1)

I want to read this manga because I haven't read it but have only scrolled through it :) Basically a guy idolizes a famous model when he first sees him and tries to become a model just like him, so that he could be close to him. But the famous model celebrity resigns abruptly which leads for the main guy to stop modeling and acting. He does smth to another couple and harasses them, but instead of getting fired he has to get trained by an otaku mangaka who draws ero-manga doujinshi. Turns out this mangaka is the famous model celebrity he looked up to. The second story is about the main characters manager and his lover. Apparantly this is a side story from another manga, who I assume is the first manga u should read before reading this manga. I think it starts of with “Honey” smth. I’m off to reading that one now, but I have to say this once is pretty decent. No it wasn’t the one that started with “Honey” smth, I can’t find that manga sadly. Maybe it doesn’t exist?
