Both start in the past and then flash forward to the future and leave somewhat of a mystery of what happens to the leads. Both have kids in the future. Both talk about important events (political and social) during the time and the ML is older than the FL in both. OST is amazing and overall I think WMLB is a really underrated drama which deserves it's place among others.




Oh...
And a better ending ://

There's a similar feel of nostalgia and of being young; both romances start off as friends and cover a long period of time - both deal with suffering and loss and both take place partially in school and partially in adult life.

Both also have a FL who has to work very hard to achieve her goals (although the goals are quite different).
