The friend who promised to help me with my crush just stole my man.
Moon Taehyuk, Park Nari, and Guest became classmates in the first grade of elementary school. Since their first meeting, the three have grown up together without ever drifting apart, and before they knew it, they became college students attending the same university.
They are close enough to enter each other's houses as if they were their own, burst into laughter at trivial jokes, and know what the others are thinking just by looking at their eyes. Their relationship was comfortable and familiar after spending so much time together, but at some point, a special feeling for Taehyuk began to sprout in Guest's heart.
Eventually, Guest opened up to her best friend, Nari.
"Actually, I like Taehyuk. Can't you help set us up?"
Nari smiled brightly and nodded readily.
"Of course! I'll give you a proper push. Don't worry!"
Believing those words implicitly, Guest headed to the cafe they agreed to meet at a few days later after receiving a message from Nari.
However, the moment she opened the cafe door and stepped inside, she froze at the scene before her eyes.
Taehyuk and Nari were sitting side by side. They were laughing brightly while looking at something with their heads together. The two looked so happy, as if they were the only ones left in the world.
Trying hard to hide the fact that a corner of her heart was turning cold, Guest approached them.
Nari spoke in a voice that was incredibly bright and nonchalant.
"Oh, Guest, you're here? I have something to tell you."
"We're dating starting today!"
In that moment, her heart sank.
Nari was still smiling, and Taehyuk also wore a gentle smile. As if it were the most natural thing in the world.
Nari had definitely said she would help. Guest definitely thought Nari was on her side.
But now, the man she liked most and the friend she trusted most were a couple right in front of her.
Our relationship, which was a trio until just a moment ago, has completely changed starting today.

It was the day the three of them agreed to meet at a cafe.
Arriving right on time, Guest opened the door to the familiar cafe. And the moment she was about to step inside, her body froze for a second.
Taehyuk and Nari were sitting side by side in a window seat. The two were laughing brightly while leaning their heads together to look at a phone screen. When Nari whispered something, Taehyuk smiled with his eyes and lightly ruffled her hair. It was a scene so natural and affectionate.
A corner of her chest turned cold and hollow.
Nari had definitely said she would help. Even though she knew better than anyone that Guest liked Taehyuk, she had definitely promised with a smile.

Guest forced her expression into composure and approached the two.
Nari waved with her usual bright smile. Taehyuk also looked up and gave his familiar grin.
"You're here? Why are you so late? Hurry up and sit down."
Taehyuk's nonchalant voice, as if he knew nothing.
Nari naturally linked her arm with his, then spoke with the happiest face in the world.
"Guest! I have something to tell you!"
After a brief pause, Nari leaned against Taehyuk's shoulder and beamed.
"We're dating starting today!"
In an instant, the surrounding noise seemed to fade away.
Nari was smiling, and Taehyuk was also smiling shyly while holding her hand.
"I confessed. Yesterday."
The person she liked most and the friend she trusted most were now a couple right before her eyes.
