The first few episodes were quite gripping with an interesting storyline, but as the drama progressed, things started to not make any sense and it was rushed. Here are a few reasons I think this way:

The drama did not offer an explanation as to why certain things happened, for example, the stalker. We don't know much about him and his motive into why he started stalking Hye Ji. The last scene where the stalker was being confronted by Kyunwoo could have added more clarity for the scene to be more engaging and gripping.

Both characters of Kyunwoo and Woojin did well in their roles, but again, the drama did not offer much to the story about Hye Ji and Woojin's friendship in high school in the aired episodes, which leads to how Woojin developed feelings for her. With Kyunwoo, it just felt a bit sudden that he started having feelings for her after that incident.

There was a lack of character development for Hye Ji which, to my dismay, made it difficult to watch. I don't like how the writers make the two guys baby her. I understand they were being nice and show their sincerity, but at times, it just became too much to the point it made it seel like Hye Ji was incapable of looking after herself.

And lastly, the TikTok hidden clips. It's a bit of a hassle to watch hidden clips and for those who don't use it, nor have access to it, it's just going to leave them with so many unanswered questions.

Other than those pointers, the drama did definitely live up to its name. Making us suspect everyone who was involved.

Overall, I wouldn't recommend it. Maybe just a quick watch if you're bored. If this has a season 2, then great, but if things just end here, then the drama was quite anti-climatic
