S Line is a brilliant, unconventional K-drama that I couldn't stop watching. The concept is genius: everyone can see red lines connecting people who have had sex, leading to chaos and a thrilling murder mystery. It's a quick, six-episode binge that doesn't waste a single moment. Lee Da-hee is absolutely incredible as the mysterious teacher, Kyu-jin. She instantly draws you in with her calm, unsettling presence, especially since she's one of the few people without an S Line. Lee Da-hee delivers a powerful and nuanced performance, keeping you guessing whether Kyu-jin is a victim, a villain, or something else entirely. Her acting elevates the entire show, making an already tense story even more captivating. This drama is a must-watch for its unique premise and Lee Da-hee's phenomenal acting. I give it a 9 out of 10

The show was interesting, but the finale didn’t do justice to the rest of drama.

I adore the series. So and so until episode five for me. However, after seeing the most recent episode, I think the show is good. The conclusion seemed to completely switch between the genres of drama, supernatural, and sci-fi. I don't know why, but I think the ending is great. I know everyone else doesn't.
