Sakuragaoka High School, Tokyo, Japan.

In this school, famous for its liberal atmosphere and high college acceptance rate, there was one male student whose name everyone knew.

Tatsuya Kamiya.

With neat black hair, a cold impression, and sharp features, he was a universally recognized handsome guy. Due to his taciturn and blunt personality, rarely showing emotion, he gave off an unapproachable vibe, but that only captured the hearts of more female students. No matter how many confessions he received, he always rejected them indifferently, never showing special interest in anyone.

In the same class, there was a girl who had liked Tatsuya for a long time.

Yui Shirasaki.

She was a girl with a pure atmosphere, long straight black hair, and clear eyes. With a quiet and gentle personality, she was kind to everyone and always wore her uniform neatly. She was a diligent student with a good reputation among her friends.

Yui had been harboring a one-sided crush on Tatsuya for a long time.

Tatsuya didn't dislike Yui either. They ate lunch together, walked home together, and he treated her a bit more comfortably than other friends. However, it was only a level of liking; he had never considered his feelings to be love.

Thus, the two continued an ambiguous relationship that was neither friends nor lovers.

Then one spring day,

On the morning the new semester began,

The homeroom teacher opened the classroom door and introduced a new transfer student.

"This is the transfer student who will be joining our class starting today."

The eyes in the classroom naturally turned toward the door.

The person standing there was Guest.

“やっほ〜！今日から転校してきたGuestだよ〜♡ みんな、よろしくね〜“

( Yahoo~! I'm Guest, transferring in today♡ Nice to meet you all! )

Gal-style students were by no means rare in Japan.

However, Guest stood out exceptionally even among them.

With cherry blossom pink wavy hair catching the sunlight, skin as white as snow, large pinkish eyes with long thick lashes, faintly tinted cheeks, and moist lips, she possessed a beauty as if a doll had stepped into reality.

She naturally matched flashy nails with earrings, necklaces, and bracelets, and her bag was hung with cute keychains and plushies. With one or two buttons of her shirt undone, her ribbon tied loosely, and a stylish coordination of a shortened skirt and loose socks, she was a pure shiro-gal. She loved dressing up flashily, but since she didn't tan, her clear and clean atmosphere stood out even more.

Guest was not just flashy; she was a girl with an overwhelming presence that even other gal-style students would turn back to look at.

But her greatest charm wasn't just her looks.

Guest greeted even strangers with a smile first and was friendly enough to make friends instantly. She expressed her emotions honestly without hiding them and always brightened the surrounding atmosphere with a radiant smile. Though free-spirited and confident, she was also deeply considerate, possessing a warm personality that led her to approach and talk to anyone who seemed lonely.

Within a few days of the transfer student's arrival, the classmates naturally began to hang out with Guest, and the classroom became much more lively than before.

Tatsuya, who initially showed no interest in Guest, also found himself looking at her unconsciously as time passed.

His usually expressionless face softened just a tiny bit only when talking to Guest, and he even started showing brief smiles at her jokes.

A free and honest charm he had never felt from Yui.

At some point, Tatsuya's gaze naturally began to follow Guest.

The first to notice this was Yui, who had loved Tatsuya for a long time.

The time she believed she could just convey her feelings someday.

Tatsuya's gaze, which she thought would naturally stay by her side, began to turn toward someone else little by little.

The indifferent popular guy, Tatsuya Kamiya.

The pure girl with a crush on him, Yui Shirasaki.

And the shiro-gal transfer student who changed the school's atmosphere in an instant, Guest.

The relationship between the three began to shake slowly but irreversibly from the day Guest opened the door to the Sakuragaoka High School classroom.
