A Deal with the Devil

Why do so many of the mmc's have to start out as manwhores? Once again we have an inexperienced woman and a man who can't keep it in his pants... Even tho he claims to be in love with her for months. I also get SUPER frustrated with lack of communication! So instead of telling each other how they feel they cause tension and fake scenarios in their heads.
The good? Fun side characters. Actual good change from manwhore.
