Intro

[Worldview Description] This story focuses on the misalignment of emotions and relationships between people rather than specific grand events.

I have loved Kim Ha-eun since we were in the same class at 17. I was always the one by her side, taking care of even the smallest things.

But there was someone else who had occupied Ha-eun's heart for a long time. A friend she had known since kindergarten.

Jung Tae-han. With his light green hair, soft impression, good grades, and wealthy family, he was someone recognized by everyone around him.

He was always kind to Ha-eun, but to my eyes, it didn't feel like he had special feelings for her. Nevertheless, Ha-eun loved him for a long time. Time passed, and on the day of the high school winter break ceremony...

Jung Tae-han leaves to study abroad. Seeing Ha-eun struggling in his absence, I began to approach her more closely.

Expressing my feelings, staying by her side, and the hours spent putting in effort for her...

One day, Ha-eun asked cautiously, "Can you dye your hair light green?" Thinking that anything was fine as long as it was a look she liked,

I changed my black hair to light green. Ha-eun was satisfied with the change, and I continued to convey my heart to her. Then, three years passed. When we turned twenty, Ha-eun accepted my confession, and we became a couple.

Our relationship seemed ordinary and stable on the surface. Dates followed naturally, and we shared each other's daily lives. But I gradually began to feel it.

Somewhere in the way Ha-eun looked at me, traces of someone else remained. Even in the moments we were together, her gaze seemed to be directed toward the past.

Even so, I did not let go of the relationship. I prepared breakfast for her, woke up at dawn to cook when she was sick, and took care of anniversaries, doing my best to keep us together.

Six months pass like that. But at some point, Ha-eun's attitude begins to change. She smiles frequently while looking at her phone, focuses on messages even during our conversations, and becomes more immersed in talking to someone else than the time we spend together.

When she goes out, she just says she's meeting a friend, but on the social media I happened to check, there are photos of her with Jung Tae-han. Photos in a sweet atmosphere. The moment I see those scenes, my emotions are deeply shaken.

That night, I was waiting to pick Ha-eun up. A late-connected call, a noisy space, and the situation I faced. There, Jung Tae-han...

He throws subtle provocations at me, creating a misunderstanding in the heat of the moment to make himself look like the victim. Seeing this, Ha-eun believes the situation before her eyes rather than listening to my words.

Words that don't reach her no matter how much I try to explain. After that day, the air between us changes completely. Ha-eun becomes increasingly indifferent to me and brushes off my words lightly.

On the other hand, she pays even more attention to Jung Tae-han, and the balance of our relationship completely collapses.

Birthdays and anniversaries are forgotten, and I am gradually erased from her life. This world depicts what kind of results follow a love that tried to replace someone else, and how a relationship with misaligned emotions falls apart.
