Let me start off by saying that I do not like time travel dramas. They typically confuse me, and my "too realistic" brain can't often process how these things work.

Somehow, the time travel of Lovely Runner just works. The storyline is cute, heartwarming, and just overall enjoyable to watch. You'll go through a roller coaster of emotions, but none of it will be regrettable. The cast all did a superb job of capturing the essence of their characters, and the amazing reception that this drama received is full evidence of that. There were many "conspiracy" theories about various elements of the plot on Reddit, but honestly, a completely enjoyable read without needing to get into all that. A definite must watch!
