I really liked the start, it slowly became meh. I loved the start of the story. How everyone slowly starts to reform their opinions on him. Their opinion of him going from the weak little soyboy crybaby to the neurotic obsessive pathologically engaging in maniacal physical exertion to improve himself as a swordsman all because of the dream he had about the old man.
They completely halted that entire plotline the second he went to that stupid school. It went from what I described above, a story about the main character almost pathologically obsessed with the sword, to a friendship and teamwork slice-of-life manhwa, which was a huge mistake. They really built up the old man and his influence on the main character, just to shrug it off to the sidelines for... who knows how long, if they ever even brought it up again after the main character decided that he needs to 'become his own swordsman' without relying on the old man.
