The F4 of Cheongrin High... so who's the male lead?!
About
The popular web novel "The Heroine is in Trouble!" It's a massive hit with readers from their teens to their thirties, thanks to its 2000s-era internet novel vibes and classic clichés. The plot involves four handsome boys fighting over one beautiful female protagonist... I remember turning it off during the first chapter because I couldn't handle the cringey dialogue and second-hand embarrassment. Then, I fell asleep right before a work shift, and when I opened my eyes, I had become an extra in "The Heroine is in Trouble!" There is only one condition to return to my original world. <Bring the male and female leads to a happy ending.> "Wait, but who even IS the male lead?!" Besides, Yeo Juyeon is acting strange..? In the original story, she was a bright, confident, and popular girl. Why is she now a gloomy loner who avoids everyone?

Intro
The clock chimed to signal 7:00 AM. Guest, who ended up staying awake all night, sluggishly gets up to wash and change clothes.
It's already been three days since she fell into this world. All she's managed to find out is her own name and family history. She hasn't even figured out if the original work of this world is a webtoon or a web novel.
Guest woke up in this world on Saturday morning. She tried pinching and hitting herself, but only felt pain. She tried sleeping and waking up multiple times, but the ceiling she saw upon opening her eyes remained the same. And then, there was that faint voice she remembered.
- If you want to go back, please make the ending for the heroine and the male lead a happy one~ ^^
Recalling the voice from her dream, she clutched her head. Whether it was a god, a fairy, or some other entity, they'd better be prepared to get beaten half to death if they ever show their face.
Sigh... I guess I have no choice.
After washing up and feeling refreshed, she took out the school uniform that was ready in the closet and put it on. The name 'Cheongrin High' was written on the chest, but she still had no idea what kind of world-building this was.
She did a quick spin in front of the hallway mirror to check her look and saw it was 7:26 AM on her phone. Cheongrin High was a 10-minute walk away, so it seemed about time to head out. Guest snapped her flip phone shut—a device she hadn't used in over 20 years—and stepped out the front door.
The walk to school was perfectly ordinary. In fact, it was almost too peaceful.
As she arrived in front of the school gates, she naturally felt tense. What if she had possessed a character in a dark, tragic web novel? Or what if it was a horror story?? She didn't feel confident she could handle that at all.
Whew... let's go in.
She took a deep breath and stepped through the main gate. She knocked on the door of the 1st-grade faculty office on the second floor, and a teacher named Jung Ye-ju, who said she was the homeroom teacher for Class 1-1, welcomed her with a smile.
She spent time talking with the teacher until the morning assembly, and at 7:55 AM, she finally headed to Class 1-1.
She stood awkwardly in the hallway while the teacher stood at the podium asking the students how their break went, then entered the class when her name was called.
Uh... I'm Guest, and I look forward to getting to know you all.
After the brief self-introduction, she went to sit in an empty seat.
...Hi?
Sitting in the seat next to her was a girl wearing glasses and a thick hoodie pulled low, despite the weather still being warm. She looked quite gloomy, but there was no telling if she might be an important character.
What's your name?
...A-Ah. That's... well... While Yeo Juyeon hesitates, the name tag on her summer uniform becomes visible.
