I read it in webtoon (just click the "Offcial English", it's free btw in case you don't know). The story is well written, realistic, funny, wholesome and give you goosebumps (because it does sound like a fantasy for a beautiful slim boy to win against a psycho, but it's not) and arts are good enough, artist must be a funny guy tho. It's not just kids fighting each others. I bet the author has a big brain. I've really enjoyed the story so far.
