Honestly I really hate it when the male lead is described as heartless and aloof but he NEVER does anything in the story! For example, I'm reading this top ranking book and the male lead is famed to be powerful, crazy, and basically a yandere in the making but when a man threatens to take his woman away, the male lead doesn't go in for the kill UNTIL the last minute and it's too late!
Or when the vampire is supposedly known to drink blood but REFUSES to drink human blood or the blood of the female lead. If youre a god damn vampire I understand you can drink animal blood but i Just roll my eyes when he goes all sappy and say oh I won't drink the blood of my beloved because I might suck her dry. Don't be shy, take a taste!
