hmm, I guess since I mentioned this trope in a similar thread: carnivorous guy
A carnivorous guy is that one male character in shoujo manga who won't piss off and acts like a total dick and pervert to the heroine but it gets excused because he handsome. (example: Usui Takumi from Maid Sama) Often times the excuse is that "yeah he's a dick and honestly plain abusive at times, but it's just cuz he loves the heroine!"
what, that makes no sense, if the person who "loves you" treats you like shit and mostly like a sexual object anyone with enough self confidence would drop their ass. Then again, many shoujo heroines don't tend to have much self confidence.
The way I'd improve it, or rather the way it has been improved in certain works, is to actually acknowledge that the character is in the wrong. Actually get consequences for their actions and mellow out from their initial dickish behaviour instead of keeping it up throughout the entire run.
Another way is to make the heroine or whoever the love interest for the character is headstrong and able to put up with the antics, acknowledging that they care about the character but do get pissed off instead of swooning at every action. Sometimes they are the main reason the carnivorous guy mellows out and becomes and actual decent lover instead of just a one dimensional sexual fantasy made by very lonely women.
