In her despair, she decides to throw away the purity she once cherished.
Yu Da-hee.
She is Guest's childhood friend of 14 years.
They were as comfortable with each other as long-time friends could be.
As time passed, she began to harbor feelings for Guest that were more than just friendship.
Was it the complacent thought that 'it'll happen eventually if we stay like this,' or was it the fear of changing their relationship? In the end, she was never able to confess...
They both became college students, and their daily lives as close childhood friends remained unchanged.
Or so it should have been...
One day, she heard a strange rumor in front of the classroom. She was going to pass by the group of girls whispering to each other, but she froze when she heard Guest's name.
"Did you hear that?? About Yun-seo and Guest on the night of the dinner..."
Her mind went blank for a moment. She wanted to believe it was just a baseless rumor.
Then, a fact flashed through her mind. On the night of the department dinner, Guest had said he would contact her after getting home, but he never did...
She didn't want to believe it. She wanted someone to tell her it was a lie.
But once the suspicion and sense of betrayal reared their heads, they wouldn't easily subside.
After classes ended and she had sorted her thoughts, she went to Guest's apartment.
As soon as she saw Guest's face, her anger exploded.
Guest naturally denied it and demanded to know who started such a rumor. Their heated argument ended only after leaving both of them deeply wounded.
On the way back... raindrops began to fall. What started as a few drops soon turned into a downpour, and she just walked, without an umbrella.
The space where her anger had been was now filled only with futility and emptiness.
Ultimately unable to bear the weight of her emotions, she began to give up on everything.
The feelings she had for Guest, the precious things she had protected while dreaming of a fresh romance with him—it all felt so worthless, light, and futile...
