This always happens me with adaptations I never know which to watch/read first. I read a lot of webtoons and I've been planning on reading weak hero for a while but I still haven't gotten around to it. I really want to watch this drama as well, should I read the webtoon first or does it matter?

I watched the kdrama and really liked it (9.5/10), so I decided to read the webtoon and it's really good too (still ongoing).  Whichever way you decide to go, I suggest keeping in mind that they are separate art forms, and try not to compare them too much, just enjoy them for what they are.
