Încă o Dată (2016)

This was a drama i watched long ago, but just remembered the feeling, It may differ in quality overall, but up until ep. 4 of Death's Game they have a similar history.

Well, I thought both dramas are kinda similar and have almost the same vibes. In both the main leads are facing relationship problems and are sent back in time for a mission.^^

In both titles in the foundation is a love story, also in both main characters are members of band. The main is that guys tries to change tragic fate of their sweethearts by returning through time. The difference is that one returns intentionally and the other not arbitrary.

Also about a couple breaking up due to stresses and conflicts, where the guy aspires to find success in being a musician.

The Day After We Broke Up is a lot less comedic than Goblin but it has a very similar supernatural/magical tone to it.

You'll know what I mean once you watch it.

Both have the lead(s) trapped in a time loop to save a life/lives.
.............................................................

Both are mini dramas with one of the leads trapped in a day long time loop.

Though not the main focus of this drama, the female lead went through similar experiences and developed the same way before meeting the male lead who helps them become happy. Both have a good look on life and development.

-Time travel to save the one you love
-Both of them are really good.

Just watch it and you will see the similarity.
