ABSOLUTELY TRUE, IT RUINS THE PLOT(╯°□°）╯︵ ┻━┻
Idk what is gonna happen in future but for now the romance is too little. I won't say there isn't any but MC doesn't give a damn abt anything except killing Odin and getting stronger for that. Females do have feeling for MC but not in a annoying way. They have their own dignity and respect MC too. Unlike some otjer action manhwa where females are useless, arrogant and overly se**lized, female character have pretty decent character. They like him and also wants to be stronger so that they can stand beside him when calamity srikes... At least, they aren't overbearingly confessing their feelings like ho**y high-school girls nor acting unbearablely tsurdere-ish.
But yes, it's up to you whether or not you should continue the story. Imo, romance is bearable for now, and can continue it.
WHY. WHY ARE ALL THE GOOD STORIES RUINED BY HAREMS. LET ME LIVWEEEEEE ･ﾟ･(｡>д<｡)･ﾟ･
