"Good Luck is a very grounded, authentic feeling book that takes what seems like standard shoujo story clichés and makes them fresh and new simply by injecting realism into them." — Billy Aguiar, Newtype USA. "Most teenagers can identify with betrayal, love, and the need to put up a false front inside school walls. If it could pick one plot point and work with it, Good Luck would be a much stronger manhwa." — Nadia Oxford, Mania. "It's a refreshing change of pace from what we're used to seeing in the shojo titles we've been offered lately." — A. E. Sparrow, IGN. "Good Luck by E-Jin Kang is a romance and drama manhwa (Korean comics), or better yet, a romantic, teen melodrama." — Leroy Douresseaux, Comic Book Bin.
