Both feature leading ladies who are very unique, and who work in video game development;

Both male leads fall in love with their rather quirky/unusual leading ladies;

Both shows have second leads who are the leading lady's childhood friend.

SWDBS and LR are romantic comedies, but SWDBS has some incredibly dark thriller moments that are lacking in LR, while LR has more melodrama/teary moments than SWDBS.
