The Effect Of A Finger Flicker On A Breakup: The Loneliness Within a Relationship
While I was immersed in watching videos featuring Hong Kyung, I stumbled upon a clip — just a short scene with a nice song playing in the background — and that was enough to make me desperately search for the title, without high expectations. I ended up being surprised by the depth packed into a single episode about a long-term relationship between Oh Jin (played by Shin Yeeun) and Cha Minjae (played by Kang Taeoh).
In the middle of their routine, during a moment of pleasure and a lost bet in a soccer match, Oh Jin receives a flick on the forehead — and that simple gesture becomes a powerful symbol. It triggers a wave of internal conflict and reflection, revealing what had always been right in front of her but ignored. Her expectations in the relationship hadn’t been met, and she realizes they don’t love each other anymore — or maybe they never did. Maybe they were just afraid of being alone and clung to each other like it was the last thing that could save them. It’s a messy relationship, but a real one.
Meanwhile, at her job in a school, the PE teacher Koo Wonbin (played by Hong Kyung) has genuine feelings for her. Even though he tries to hold back, he’s transparent. He shows up like a breath of fresh air, comforting Oh Jin in her struggles without pressuring her or demanding anything.
The minutes I spent watching brought me so many reflections about that feeling of being alone in a relationship — when only one side is truly invested, when one person looks at “us” and the other only sees themselves. It’s suffocating not to exist in a relationship.
“Staying is hard, but leaving is even harder,” says the protagonist’s mother. She doesn’t sugarcoat the truth, but she encourages her daughter, showing that even when it’s tough, she still has a choice.
