the fl isnt random at all... especially since she shows up almost at the very beginning and started building friendship with the mc. Same with the fighting scenes, idk maybe u expected pictures to suddenly start moving, but its good??? Idk what u meant by people stand around and talk.. do u mean the students or bystanders??? What, do u want them to start risking their lives and start fighting, not building up the storyline at all, completely leaving the readers in utter confusion?
Woah... sorry but, i really disagrees with you hehe. The plot is good and how the characters are having interest with the mc is natural in a way. And the fighting scene is already detailed. Chop chop, they are not just standing and talking when they are fighting. do you just want a mime play when they are fighting? Where's the fun~? Also, i'm not interested in romance when it comes to action genre manhwas, but this one is an exception because their romance isn't cringe and the fl is NOT random. She is where she is, if you understand the story. i could see that the story line is pretty good, and the mc's personality is interesting as well. Ehem... Have a nice day (⌒▽⌒)
Its has all the silly cliches and rushed storyline troupes you could ask for. Random female character love interest that makes no sense, poor fight scenes where people stand around and talk, typical shallow minded people, etc. Mediocre at best.
