Ranker Who Lives A Second Time : https://www.mangago.zone/read-manga/ranker_who_lives_a_second_time/ (it's the classic overpowered mc but the plot and the mc's background are actually interesting though i think they stopped uploading new chapters)
The S-classes That I Raised : https://www.mangago.zone/read-manga/the_s_classes_that_i_raised/ (this is a really popular one so you might've read it but it wasn't listed in the replies so i tought i would, the story is really unique and interesting also the characters are so funny)
Poison Eating Healer : https://www.mangago.zone/read-manga/poison_eating_healer/ (this also has a very different story compared to others and it's good in my opinion but this one hasn't been updated for a while either)
SSS-Class Suicode Hunter : https://www.mangago.zone/read-manga/sss_class_suicide_hunter/ (literally one of my FAVS the story is really original the mc has a really good character and it's a must read)
The Dark Mage's Return To Enlistment : https://www.mangago.zone/read-manga/the_dark_mage_s_return_to_enlistment/ (this one is soo underrated i'm literally in love idk why noone's talking about it, the mc is so funny the story is new and refreshing, i definitely reccomend it)
I got this list from someone else but its all manhwas with overpowered mc : https://www.mangago.zone/home/mangalist/280075/
guys i just finished reading solo leveling and i don’t think i’ve ever loved a story so much. i need to read anything and everything that’s like it (story and art skill wise) because i’ve been shook to my core. PUH LEASE GIVE ME RECS. maybe even some with more romance!
