Can anybody recommend me something of high school genre where mc is actually different from what he/she seems in school and surprises others when they get to know him /her or is actually very intelligent/smart/powerful than how he/she seems in school to everybody.

I was never into manhwa a few years back cuz I found most of them to just be smut with no plot. Literally smut 5 chapters in a row. But because more and more manhwa were uploaded and the entire popular pages now ONLy consisted of manhwa, I have to change my taste and adapt. Now that I'm used to the format of manhwa for 3 or 4 years, will I have to go back to mainly reading mangas/manhua from now on... Anyways, I've been reading on this site for 7 years or so now. I don't want this to be another case of mangarock.
Better to just remove the korean bls, they're not targeting that many stories. I still want to read my reincarnated female lead stories on this site. Let's go back to finish uploading the unfinished jpn bls. It's been forever since sekaiichi hatsukoi, honto yaju, Koisuru Boukun and all the OGs were updated. We'll be old and these stories will be left forever unfinished on this site at this rate.
