This has fluffy romance, comedy aplenty and a lot of heart. I can't believe that within 10 minutes into the drama, I was already crying with Im Sol. Kim HyeYoon delivered such a great performance in the first episode that before it ended I was hooked.

The story is about Im Sol (HyeYoon) who was about to give up on life after an accident. Because of the encouragement she got from an idol Ryu SunJae (WooSeok), she decided to live. For more than 10 years, she supported SunJae as a fan and was very shocked when news came out that SunJae died from apparent suicide. A mystic occurrence brought her back in time when both she and SunJae were still in high school. Can she stop SunJae's death? Was it really a suicide?

As of writing this only 2 episodes are out but I am already enjoying this drama. In fact, the last few minutes of Episode 2 gave me overexcited butterflies. Scenes that may seem cringey on paper turned out lovely and sweet because of the music used and the chemistry between HyeYoon and WooSeok. And then there's also GeonHee who's playing the second lead. He also looks good with HyeYoon. But I'm still team SunJae. The scriptwriters so far made somewhat believable scenarios (yeah, I will also run/get scared when a person seems crazy). I am looking forward for the next episodes.

Edit:
I am now at episode 8, my favorite thus far, and this just keeps getting better so I'm changing my review score from 9.5 to 10. This deserves it for making me look forward to Mondays even though it's the start of my work week. Now I'm not just on the Sunjae-Sol ship but also on the WooSeok-HyeYoon ship too. These two are really lovely together.

Edit 2:
After completion, this has become my standard for a romcom and has become my favorite drama of all time. I would rate it more than 10 if I could. This has everything like a mashup of all possible drama tropes (running after a leaving car, time capsules, etc) and settings (jungle scenes, island scenes, school scenes, the ever present airport scene, etc) but still done right. I kept thinking that the writer has a checklist to see which ones she haven't used yet. I love all the OSTs, they are used at the right timing throughout the drama even the BGMs. My favorites are "Gift", "Sudden Shower" and "Run, run". This also has the best pacing among all the dramas I've seen with the focus mostly on the leads. Its romance is satisfying and was not stingy at all with the kiss scenes unlike usual kdramas. Its comedy despite a few misses are ones that remain funny even in a rewatch. Its logic as a time travel drama made sense. There are detail consistencies in the interconnected scenes like scars, head bump, etc which shows that this had been meticulously made (yeah, I had a minor issue with 34 yrs old Sunjae's haircuts but it's negligible cause he looked almost the same anyway). There was a time in Ep13 that this drama broke my heart but immediately fixed it again in the next episode. It is a self-aware romcom and often references itself with parallelism and easter eggs that are spread throughout the entire drama. As such, it makes you want to rewatch previous scenes and episodes. It shows again and again that the leads have an interconnection that time and distance cannot truly sever and how selfless is their love for each other. I'm so glad that I chased this because I was able to discuss theories and ship the lead couple with fellow capellas (eclipse fandom) and subeoms (solseon fandom). I know I'll rewatch this again just for the comfort it brings.
