if not then please give me some manga which contains delinquent(s). - Boy or girl or maybe both.
It can be yaoi too.

Second manga which i would like to read should be like Black Haze, more superpowers/paranormal and such things. Almost no romance in them please.
Comedy won't hurt.
It's perfect if main chara is strong but may hide it from others.

There is this hilarious manga with many characters being deliquents: Yankee kun to megane chan. Highly recommended.

The pic looks like It might be from a Webtoon. I feel like I can almost place it but it escapes me. It's all over pinterest though. Maybe google search the image and see if anyone tagged it. I could also be fan art so... 😳

Delinquents
GTO and it's prequels & sequels
Kyou kara Ore wa!!
Angel Densetsu
-I personally would not recommend Yankee kun to megane chan cause the ending is bad/rushed and it's not so much about delinquents.

Superpowers/paranormal
xxxHoLic
Kekkaishi
Soul Eater
Dawn - Tsumetai Te
Psyren

There's a manhwa "Change Guy".

I'll focus on shoujo-ish romance mangas with "bad boys"/"bad girls", I doubt you really want mangas about delinquents :

Yasuko to Kenji
The Kidnapping of Minja Jo's Boyfriend
Hana-kun to Koisuru Watashi
Akuma de Sourou
Junai Tokkou Taichou!
Atashi no Banbi
Tonari no Kaibutsu-kun

I read Black Haze, and I think Trump and Crepuscule remind me of it, though the main character doesn't really 'hide his strength' (cause he doesn't know about it)
Also sorry, I'm not really sure on how to do the the tag thingy on the manga

To answer your question about the pic
