I have waited for Mayoke No Darling to be updated for a year now and its finally out!! Happy day for me 😃 but that not what I wanted to ask for..

I was wondering if oooo you great ones out there know any other manga with similar theme? - Where a scary looking guy met a total opposite, clueless type of guy? The clueless guy doesn't have to have an adorable face or anything, he just sort of have to be different from the scary dude - personality wise.

Kinda like Nirameba Koi .. The scary guy don't have to be a delinquent either, he can be a senpai, a kouhai, a neighbour, a teacher, etc etc.. you know, he can be whoever.

P/S: NO shota please ~

The opposites-attract couples are always so cute!

Hidoku Shinai de Nerdy and a delinquent.
Usagi Otoko Tora Otoko Doctor and a yakuza.
Hatsujou Animal Student and delinquent.
Houkago no Love Call Teacher and a yakuza

These aren't probably what you are really looking for, but I'll link them just in case:
Honto Yajuu Police officer and a yakuza. This kind of fits with what you want. Yakuza guy isn't really scary, but the couple does face obstacles with their differences.
Katekyo! The scary guy (seme) is more intimidating and bullies the uke. He's not scary like the guys in Mayoke or Nirameba, but the uke does have some sort of fear with what the seme will do.

Check out the Opposites Attract tag for more. In that link I've filtered it to only show Yaoi. You might find some good ones in the Scary Seme tag too!
