- Same Male Leads - CHANYEOL /(^3^)/
- Both of the story lines are really fluffy and cringe, with no deeper meaning. Also both stories are pretty predictable
- Same Male Lead 'vibe' , the male leads both had the mean facade and treated the girl really badly at first
- REPEAT Same Male Leads - CHANYEOL /(^3^)/

Overall both were really enjoyable, but woudn't be the type of drama/movie I would stay up until 5am watching.

- They both have that 'comic' vibe to it
- Smart Male Lead
- Not your stereotypical and naive Female Lead
- Both stories are really fluff\y, but My Amazing Boyfriend is a bit deeper at the end.

They both are based on the same story, Love O2O is the drama version and One Smile is Very Alluring is the movie version. Honestly the movie version went by to fast, and it didn't live up to the drama version.

Both of the stories are really unpredictable. W and Liar Game (Korean Remake) Keep you hanging, although W has 16 episodes and Liar game has 12 episodes.. which is really sad because I wished it was longer...
