Blue Birthday

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

without the time travel, they seem pretty similar and have the same vibes .............................................

The leads travel back to the past in both dramas (although for separate reasons)
both are high school dramas
male leads in both dramas are optimistic

Both dramas talk about how female leads are high schoolers and have been traumatized by their past birthdays due to events that had happened on that day. They slowly try to figure out what actually happened on that day with the help of the male lead.

Both dramas are high school teen stories with Similar editing style, coming of age stories, about high school students and their relationship

Both are school drama......
Both story contain return to school.......
Both drama have sad scene.......

Both are short length dramas in which the leads are classmates and right when one is about to confess, the other dies tragically. The remaining lead discovers some objects left behind (photos vs. candles) can be burned, allowing them to travel back in time for a little while each time. They then try to change the past and save the person they love.

Both drama have school mystery and struggle of student.............i find them Similar...... That's it!............

Although different in genres and setting (Blue Birthday is a high school based romance, 365 is more pure thriller), they both have a similar premise of going back in time to save a loved one. They also have some similar twists (although I wont say more so as not to spoil). Blue Birthday is more light-hearted while 365 is more dark and suspenseful, but if you're looking for a similar set-up and don't mind the tone changes, give it a go!

similar plot/
in let me off the earth male lead experiences time loop and trying to change the story that happen again
in let me off the earth male lead knows whats going to happen in next and even in blue birthday female lead knows whats going to happen next and trying to change ....

In both dramas there is time travel: in Blue Birthday by burning a photo, in Nine by burning a stick of joss.

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

Both are mini dramas in which the FL time travels to the past/her school days and tries to change the past to save the ML who she loved and who died back then.

IDK why but they do give exactly the same vibes!!

~ Revenge
~ Pain of loss
~ Highschool slowburn love
~ Couple’s chemistry
~ School love and separation
~ Memories of past
~ Mystery
~ How they couldn’t getover what happened
~ Storyline goes in past and present
~ Flashbacks of the dead person and regrets
~ Living with pain and fury while you are still alive

If you’ve seen one of them you should watch the other one for sure!!

If you want to see a romance drama that uses magic photographs to to revisit and travel to the past. the big differnce here is that history can be changed and altered here.
