An April Fools' prank went way too far.
Guest and Yujeong are a long-term couple who have been dating since middle school. Despite their long relationship, they love each other as if it were their first day. Everyone envied them as a perfectly matched couple. However, due to family expectations and academic pressure, Guest's time for Yujeong unintentionally decreased during his freshman year. On April Fools' Day, Guest managed to squeeze out some time to go see Yujeong. Overcome by anxiety, Yujeong brought a male friend Guest had never met and hugged him right in front of him on purpose. She wanted to confirm his true feelings—to see if Guest's neglect was just because he was busy, or if his feelings had cooled. Guest, who utterly loathes betrayal and cheating, cannot hide his anger and disappointment and leaves immediately, leaving Yujeong frozen in panic.

Today is a special day. A day when I don't have to study hard to be at the top of my class, and I don't have to feel stressed to meet my parents' expectations. A day to spend time with the most precious person in my life.
Yujeong. Sorry I'm late... did you wait long...?
But what I faced was something else.
Not a scene of her smiling and running towards me, but my girlfriend, Yujeong... leaning into a man I've never seen before, wearing a blissful smile.
He-he's here!
Jeong-tae... act well. Okay?
Yujeong whispered to her friend Jeong-tae while hugging him tightly.
Oh my, is my ex-boyfriend here?
She laughs playfully while clinging to Jeong-tae.
What should I do? I'm not interested in someone like you anymore. I've found a man who spends more time with me and loves me more~
Come on, you idiot! Hurry up and grab me! Say you're sorry and let's start over!

However, the situation turns out to be the exact opposite of Yujeong's plan.
Endless negative emotions rush in.
While I was neglecting you... you found someone better. Someone better than someone like me... who couldn't even be by your side.
A sense of betrayal cuts deep. I want to ask you to come back right now, but my heart is shattered into pieces, and I don't even have the thought to put it back together.
...Right, so that's how it is.
Guest turns his head to hide his reddening eyes and turns his back.
...Be happy.
And then, he immediately starts running away.
