I am writing this review as someone who hasn't read the webtoon.
I am someone who really enjoys revenge plots, it feeds my soul to see bad people be put in their place, however, this drama, on many occassiona, just had me feeling frustrated instead of happy.

What I liked
1. Wonderful performances by supporting cast - I love almost most of the supporting cast of the show, including actors portraying Sumin and Jihwan. To pull off villains that make your blood boil is not an easy task and these two nailed it. It was genuinely infuriating to see them manipulate and gaslight Ji-won.
2. Jiwon learning to stand up for herself, and face Sumin on her own as much as she could. It was nice to not have Ji hyuk be her knight in shining armor all the time.
3. Jihwan's death, it was satisfying to see him die the way Jiwon had, instead of it being Sumin. It was a plot twist I enjoyed.

What I disliked
1. The main leads - I disliked both of their characters, especially Jiwon's. Her pure and naive personality felt unreal and stupid and instead of pitying her situation, I only ended up feeling mildly annoyed at her decisions. Even after time traveling, she continued to take forever before she grew a spine, and by the end of it, I was rooting more for Jooran than her victory. Jihyuk's character was the blandest male lead one ever had in kdramas. Having his entire existence revolve around Jiwon's happiness made him one-dimensional. Surely, they could have explored his relationship with his fiance in detail, and explore his arc. He basically was like just there.... most of the time, and it was boring to watch him on screen. The chemistry of the main leads also was lacking, and I was left feeling uncomfortable whenever they hugged, because of how forced it felt.

2. The writing taking a nosedive after episode 11. I didn't mind the addition of Yoora to the plot, they needed a scapegoat to share Jihyuk's fate, while also being connected to him. But damn, they failed the execution. Her character too had no depth, no rational explanation behind her motivation other than she was ruthless... which we didn't actually get to properly appreciate because of the lack of context. Also it didnt make sense why she would use Jihwan considering how pwerful she is, let alone sleep with him and bail him out of jail. Crappy writing.

3. The fact that no one stands up against that shitty manager, its so irritating. Surely someone would have, it just felt so ..... weird that everyone just tolerated that behaviour. Surely Jihyuk's sister could have had him fired, especially since he underperforms.... it was stupid.

Overall.. this was a one time watch, and I played most of it in 2X speed.
