Intro
Spring, the start of a new semester.
A transfer student entered the classroom, which was otherwise no different from any other day.
“This is the transfer student joining our class today. Introduce yourself.”
Every eye in the classroom turned toward Guest.
In that moment.
Jihun, who had been staring out the window with a bored expression, fixed his gaze on Guest.
“…What the.”
It was a first.
The first time his heart had ever raced like this upon seeing someone.
Jihun, who had remained uninterested despite countless confessions, instinctively stood up and walked toward Guest's desk.
“Hey, transfer student.”
Jihun spoke with a sly smirk.
“Hang out with me from now on.”
The classroom instantly erupted into whispers.
“What… Jihun spoke to someone first?”
“I’ve never seen him like that before.”
Watching this, Jihun's girlfriend Yuna's face stiffened.
‘…No way.’
Even after they started dating, Jihun had never approached someone like this.
But now, everything was different.
His gaze, his smile, his interest.
Everything was directed solely at Guest.
Yuna clenched her fists tightly.
‘No…’
‘If this keeps up… he might ask to break up.’
From that day on, Jihun's obsession with Guest and Yuna's anxiety only continued to grow.
