I ended up watcgphing this drama because i saw a funny scene of lee yi kyung in this drama on a variety show.
As soon as i watched it, i agreed that the story itself is funny ^^. But also sad at the same time.
All the actors brought the emotion up really good, especially Jang Na Ra. (I cried a few times 😂).
The story isn't too heavy. But still, unpredictable.
So, i highly recommed "go back couple".
P.s. i was really impressed by how they brought up the youthful life ^^
