This drama fully entertained me. It has some very good looking actors, lots of laugh out loud moments, an interesting storyline and all of the characters have different quirks which makes it a very enjoyable watch.

This was also the first time when the OST didn't bother me. Most of the time if an OST is repeated several times I just get bored and it soon starts to annoy me, but in this drama (even though I don't remember the name of the song) it made me happy every time I heard it.

The story itself was really good, although I feel like some moments need a little more work on them, like for example, when Im Sol went back in time and she could walk again, she only acknowledged it for an episode and moved on. I think that if a character truly spent over 5 years (and most likely more) in a wheelchair, they would need more time to readjust.
Also, I feel like this drama could have been a tad bit shorter. The time travelling kind of reset all of the progress that Im Sol made and it frustrated me at times, but the ending truly won me over and I couldn't care less anymore, they were happy and so was I.

Also, it is never explained how every time Im Sol went back in time, her grandmother hinted that she knew about it and didn't tell us further.

Besides a few characters that need a bit more development and a few story loop holes, it's an entertaining watch that finally got me out of my drama slump. If you want to watch it, go for it.
Side note: don't form your opinion based on a random persons review. Whether I liked it or hated it, you need to watch it for yourself and form your own opinion.

Happy watching!
Thanks for reading and have a good day.
