Can someone recommended me some title similiar with this one

the golden haired elementist, it’s not exactly similar since the MC is an elementist and doesn’t use the sword but it feels very similar

I would not recommend this it was left on a cliff hanger and disconnected.

MC like Airen where he not OP from the start and he work hard to grow stronger.

yeah but it’s still worth a read, plus you can read the novel or something??? it’s my favorite though so maybe i’m just biased

It’s about magicians but the main characters are similar in my opinion :)

I would say the reincarnated assassin is a genius swordsman. It's different, but similar with learning the sword and the dynamic between the trainee class.

This one has a horrible fl though but thats also jus my opinion cause I dont fw bitchy romance leads
