Liar x Liar is about a girl who ends up sort of by accident dating her step brother while in disguise, so he had no idea its actually her.

I'm sure you can already tell from the premise that it's one of THOSE rom-coms, the type with utterly ridiculous comedic situations, that many will find off putting for secondhand embarrassment, or because they find the main couple unlikable because they're always lying to each other. The thing is, I usually dislike that type of rom-com also, but I actually really liked Liar x Liar.

I'm sure there are plenty of readers that will not be able to get over that premise and the fact that she is lying to her step brother, but I personally thought the author was deftly able to handle the tone of it that it never quite got to the point where I would normally think it distasteful. I think it really helped that the protagonist is constantly giving her best friend updates to seek her advice in this ridiculous situation, meanwhile you can practically see her friend kicking back and getting out the popcorn. It helps to reinforce the idea that this is all very ridiculous, and not to be taken seriously.

But then, in the last third or so, Liar x Liar really surprised me. The protagonist had to finally face realistic consequences for her actions. It really made Liar x Liar go from a ridiculous kind of trashy diversion, to legitimately really good.

This isn't a manga for everyone. As I said, many will be too turned off by the initial premise to want to read it. But if you can accept it for what it is, I think it's a very well done rom com of its type.
