If you like to read anti-hero stories (like me), I suggest you to go read Supreme Magus LN. The beginning may seem boring and the most hateable character is 100% the Main Character himself but it gets better and (don't know if you like but well) the magic system and magitech is really out of this world (no pun intended).
Ps: the Academy Arch was probably the worst of them all but with perseverance you can get through it =﹏=
I'LL FIGHT YOU ヾ(☆▽☆)(๑•ㅂ•)و✧ ( ̄ε(# ̄)Σ but I do agree that stuff like that takes away from the story. If you gunna write a story with people that actually behave like actual people then dont solve a problem with the "Power of friendship and goodness." But in this situation that's not the case cause I understand why the author ended Snows conflict the way they did.
I can see where you're coming from.
Hanbin seems to have hero complex, which is sometimes annoying but overall fine bc he's his strength going on for him (unlike shun from kumo desu), and most of the characters are self-absorbed to the point it's irritating and they don't have an ACTUAL talk unless it's a) a useless narrative during fights or b) to expand the plot. I swear some arcs will be shorter if only they sit down and hear each other out instead of instantly going head to head.
Then again, it's not uncommon in shounen mangas/manhuas/manhwas. You're bound to find those "power of friendship", "only do good" shits. Should've already expected them before reading this. Imo this is still a good read tho

Okay the fight was lit but...
Snow's redemption arc was fine (okay, i shed a tear, i admit) but...why do I feel "friendship is the solution", "only do good things" and "you can't save the world if you do something immoral" vibes? ಠ_ಠ I don't like that stuff. Come fight me
