Twelve Letters

Just that… I don’t really have any explanation but both drama gives a similar plot and vibes, including:
- tell stories about parents and child
- slice of life
- poverty… (believe me no one can deny me with this one)
- love for one another (way too dearly)
- sharing things
- caring
- make you in tears… I don’t usually cry but… these…. ???
Welcome for those that came up with another reason…

Well,,,
Here me out… surely we have two different ending for both series but surely we have this similar plot serving here~~

First thing first… the whole ironic story of the leads… the girl for sure are so pitiful and poor… they just had to face EVERYTHING!! I mean EVERY SINGLE THING… they are keep going on trouble trouble trouble the scriptwriters just can’t leave them alone… One single happy things happen to them would lead to another disaster…
And next we have the downbad loyal whipped male lead…
You can’t tell me otherwise… one wait for 10 years while the other wait till….?????

Sure things they want to escape the reality and ALMOST SUCCEED!!!
But again our scriptwriters just decided to, “Nope, they can’t have the peace that easily”
SERIOUSLY??!! I’m getting immersed…

All in all I love both series with their own charms.. very interesting one ???

Very different plots, similar characters/main relationship. Both dramas have two lonely, poor, and damaged leads - a FL struggling with issues with her family and an orphan ML who works hard jobs - who become each others' family.

Both Twelve Letters and Yesterday Once More have that same bittersweet, nostalgic feeling. They’re not just about love, but about how time changes people and relationships. In both, the romance isn’t straightforward; it’s tender but marked by distance, regrets, and missed chances. They focus on memory, growth, and the way small moments stick with you over the years. The tone is slow, emotional, and reflective, making you think about your own past and the “what ifs” in life.

Both shows feature the younger generation heavily involved in uncovering or altering the tragic timelines of their parents (or parental figures). Both uses dual timelines, In "My perfect stranger" the daughter time travels into her parent's past timeline.
Both features the suspense and mystery elements as catalysts for the plot and MPS shows less traumatic events compared to TL with solid happy ending.

Both are about two damaged kids who make each other their only family. Both MLs feel they have no future but the FL does and sacrifice a lot for her. Both FLs fiercly love the ML. Both dramas have a gritty, serious, and realistic feel.
