Hello can you please recommend to me a manga/webtoon similar to this one ? thank you in ad...

ELECEED AAAAH.. . IT HAS NEKOS TOO!

GOD OF BLACKFIELD

If it's similar then it would be designated bully. High school theme, OP lead, a lot of bullies and kicking a$$es, annoying harem, and freeway plot

Weak hero might be to your liking.
