This series is sooo short, it's among the shortest dramas I've watched!

This is also one of my main complaints: I wish this series was longer :(

But overall, I liked the format of the series, although the game aspect of looking back at their past felt a bit gimmicky to me and I wish that they'd showed more of their relationship in the past as it truly was because it also made me a bit confused.
Anywho, the production really made good use of the limited amount of time they had making the series have a good balanced ending but with a bit more time I know they could've gotten a bit more potential out of it.
I still liked the series because the acting was excellent and the colours of the series were super pretty.
