Operation Proposal (2012)

Both dramas tell the romance between two best friends and show the difficulty of being sincere about their feelings, because of the fear of lose their friend.

Both best friends falling in love, and missing opportunities to confess

they both have a similar theme of best-friends developing love... eventually.

They're Both About Best friends, and both involves baseball!

It's the one hour special of the Japanese version proposal daisakusen .

In both dramas you travel to the past through photographs in order to conquer your first love........

Going back to past for her first love. Limited chances to go back. In Operational Proposal also Male Lead go backs to meet Female Lead to propose. But He loses chance then he go backs to propose. Same as Blue Birthday there are limited number of chances to go back to past to modify present

As our main plot is time traveling, both dramas are about this. It's different in many things. This is about a man who time travel to propose his first love and to stop her from getting married.

events in both films take place in the baseball world ..........

Another best-friends falling in love drama! But, this one has some sci-fi to it. You'll know when you watch it. ;D

this is the korean remake of Proposal Daisakusen which the the original version of this drama.

- both contain time travel
- both centered around main lead trying to right his wrongs
- main leads are both self-involved, love themselves a lil too much n don't think they're doing anything wrong

Same story - Guy has been loving her friend for a LONG time but stayed as a friend.

They are both similar with the time travelling part of it, but Enoshima Prism is more friendship based whereas Operation Proposal is more romance based

Both about childhood best-friends falling in love
