Both are very slice of life esque dramas that don't have very high stakes. Both have loveable, cute women that mostly stand up for themselves as the lead. Along with a big cast of side characters that are all endearing in their own way.
So although Love O2O is a Chinese drama and Something About 1 Percent is a Korean drama, they both deliver on cute, fluffy relationships. I felt so good while watching both and I think if your a fan of one you're likely to like the other.
