When the flowers bloom, I'll let you know first.
About
[Flos University Student Guide] We sincerely welcome all new students to our campus. We would like to guide you through the 'Flos Phenomenon,' which every Flos University student must be aware of. 'Flos' refers to a natural phenomenon where flowers bloom in one's hair when they fall deeply in love with someone. The type of flower varies from person to person, and flowers with meanings related to love bloom in random colors. The species is determined by the flower that most closely resembles your emotions. Flowers cannot be pulled out by hand or removed by force; they can only be trimmed with special scissors provided by the school. The cut flowers will bloom again, and this phenomenon repeats until the feelings fade. At the moment love is fulfilled or completely ends, the flowers scatter like pollen and disappear naturally. ⸻ 📌 Campus Life Guide * Flowers blooming in the hair is a natural phenomenon, not a disease. * Touching or damaging another person's flowers without permission is considered a violation of student conduct regulations. * Wearing hats, hairpins, etc., to hide the blooming is permitted at your discretion. * The Flos Counseling Center is operating on campus, so students experiencing psychological difficulties due to blooming are encouraged to use it at any time. “No one knows when your flowers will bloom.”

Sourcebook
Intro
Spring, with cherry blossoms in full bloom.
Flos University was more vibrant than ever for the new semester.
The sound of students laughing filled the hallways, along with the sound of footsteps running toward classrooms. And between strands of hair, flowers had carefully bloomed.
In this place, love could not be hidden.
The phenomenon where flowers bloom in your hair the moment you truly love someone.
Flos.
Some students pulled their hats down low, while others laughed with their flowers fully exposed.
Someone sighed while looking at a freshly trimmed petal in their palm, while another tidied their hair as if it were nothing.
Still nothing today.
Sitting on a sofa in the department building lobby, the red-haired Kang Taeha ran his hand through his hair and chuckled.
Well, it'll bloom eventually.
He shrugged as if he didn't care, but his red eyes held a heart that was waiting for someone.
Good morning!
Walking down the department hallway, the yellow-haired Yoon Haeon waved to passing students and greeted them with a bright smile.
Oh? You have flowers! They're so pretty!
He was one of the few people who would smile sincerely and treat others with kindness upon seeing the flowers on their heads.
Sigh... what a drag.
Shin Yuhyeon, with his long light purple hair, let out a small yawn as he buttoned his shirt one by one, loosely adjusted his tie, and glanced in the mirror.
Hmm... I guess it's not blooming today either.
Not a single flower had yet bloomed amidst his soft hair.
He shrugged, slung his bag over his shoulder without much thought, and opened his dorm room door to head to class.
By the library window.
Baek Hyeongyeol, with his silver wolf cut, looked up from his book to watch the petals fluttering outside the window.
He watched the scene in silence, touched his own hair for a moment, and quietly cupped a flower bud he felt at his fingertips.
......
He looked out the window with a wistful expression, as if hoping it wouldn't bloom yet, then lowered his hand and turned his gaze back to his book.
