I need help searching for a manga I read a while ago. I want to re-read it but can't seem to find it anywhere. I'm not even fully sure whether it was a yaoi or a shounen ai.

The only things I can remember are;

• There was some kind of supernatural element ?maybe vampires
• Set in current time
• The seme defiantly had a brother who was the head of the household. I think he also worked in the entertainment industry as I recall part of the scenes were around sets and actors but non of the main characters were actors, they were more behind the scenes kind of work.
  -I remember one scene where the uke came into contact with the seme's brother in a dangerous situation ie - brother wanting to kill the uke?
• Some kind of auras in the manga because the uke literally froze when coming face to face with the brother.
• main character I think was clumsy - had a cast at one point - could potentially be making this up or maybe he just kept getting into dangerous situations?
• It was a long manga

I know its not a lot to go by. I've been searching myself for hours and coming up blank.

Thanks for any help.

A few questions.

-Was it black and white or color?
how long is a 'while' 1 year? 5 years? 10 years? (estimates are fine ex: at least 2 years but probably 3+)
-Did you read the entire thing?
-Did you read an official translation?
-Is long 10 chapters? 30 chapters? 50 chapters (estimates are okay ex: >10 or ~20-30 )

-Do you remember anything about the art style? (the more modern realistic or the older styles?)
-Do remember hair colors/textures/length of the main characters? (long, short, curly, wavy, black, white, brown, pink etc)
-Age gap?
-Significant height difference?
-Stereotypical larger dominate seme with shorter/thinner 'feminine' uke?
-hobbies?
-high school student? College/University Students? Working adult? NEET?
-poor? Rich?
-Anything else about the physical appearance or occupations of the main characters? (if you aren't sure please still include it but make a note saying so)

-How the main couple meet?
ex: coworker, customer, school campus, classmate, job interview, at a movie theater, teacher, at a park, living close to each other, convenience store, through friends or family, getting into a car accident, bump into them, music concert, bathroom, party, karaoke, dark alley, robbery, gangster calling in a debt owed by missing parents, etc)

-Age gap?
-Significant height difference?

I read it about a year ago.
No idea what the main characters looked like. Maybe the uke was blonde and the seme black haired but I could be making that up. I don't remember if it was in black or white or in colour.
I remember there being heaps of chapters - more than 50 but unsure how much

The main thing I can remember is that there was some kind of work around sets. Like I'm unsure if the protagonist built them or worked behind the scenes? I remember the brother was the head of some entertainment agency. I am aware there isn't much to go on here. I myself searched and searched but I can't find it and now its frustrating me.

Is it The Sweetest Man

Main Love interest is Vampire (Seme)
Seme's father (lets call him ML's dad) gives off a 'domination' aura that overpowers pretty much everyone vampire and human (the ML's dad looks same age as his son)

ML's dad is an actor (or is pretending to be with brainwashing its kind of hard to tell). The ML's dad also tries to manipulate his son using the uke (with violent methods)

Protagonist (uke) makes costumes

Uke is blonde, ML is black haired

The ML's brother also appears, he has the 'domination' aura as well

100+ chapters
