My guess is that Doowon got hurt pretty bad or had to move away because of Taehoon and/or Moonsoong and with both parties feeling guilty they changed and along the way dyed their hair like Dowoon
It would be hypocritical of me to comment about the art (as I have no skill whatsoever) but I will comment on the inner monologue of the MC being on the verge of being a wall of text. So far, it's a 7-7.5/10 for me
Hoping to see more of Malphas and her being more fleshed out on why she was talking to Cavalier Angelo rather than a boss fight with no particular reason
How is there so little reads? This is a damn good series. The action is great and easy too follow and art is great. We can't say much about the story with the little dialogue and backstory so far and it may lean too heavily on shounen battle manga tropes but none of those are big deal breakers.
