What if your worst enemy turned out to be your sister? Dark loner Haera and golden child Li-on have always been arch rivals, competing to be the best in their arts high school. Of course, Li-on always seems to win, with the support and privilege provided by her wildly wealthy, world-famous sculptor mother. Then again, Li-on has dark secrets of her own, and there's just something about Haera—her authenticity and vision. Will Haera and Li-on ever make peace? After all, there can only be one when it comes to the real deal. (Source: Webtoon Entertainment)
