Idr means i dont remember
I dont think this on tapas so this is potentially off topic.
Main character - blonde hair and kinda rough looking
Main male lead - black hair who looks rather neat (idr)
The bully - black hair and i think shaved at the sides
The character the bully is in love with - long black? or blonde hair up to his shoulders. I think he had a pill addiction towards his heat and overdosed at one point in a chapter
(THIS DESCRIPTION IS NOT 100% ACCURATE. THE WAY IM EXPLAINING THIS MAY NOT EVEN FLOW CORRECTLY AND IT MAY JUMP FROM ONE SCENE TO ANOTHER. IM JUST REMEMBERING THIS FROM MY BRAIN. )
there is this manga yaoi that i been trying to find and it's set up in omegaverse. It starts off with a high? or middle school boy who is going to get tested if he is an omega beta or alpha. This happens with his classroom and he founds out he is an omega. He panics that he is an omega as he knows omegas are the weakest and he is popular with his friends. He lies to his friends that he is an beta or alpha? I don't remember. After he get his meds for upcoming heat(ider if he had heat already or not) and he slowly loses contact with his friends as he is ashamed with his status as an omega. That is just the start.
All i remember reading this is that it doesn't follow the trope of omegas and alphas submitting to their destined mate as the story soon breaks off into a slice of life thing? Idek but the main character has already been marked (forcefully) on a school rooftop by the main male lead and there were bullies watching them.
It turns out as a new character is introduced when the manga goes into the slice of life genre, the main character destined mate is supposed to be with the bully and the bully's lover(the soon to be lover who is the new character) destined mate is supposed to be the main character's male lead. Its all the opposite and they found out when the new character heat was taken in place and began to find his mate who was nearby.
I REALLY love it as it was different from other omegaverse manga because it didn't follow what t their instincts told them during scenes with heat and rut. i wnat to find it again though but i forgotten what it name was.
