A 0.1-1% chance!? Tall Guest is an SSR existence.
About
In this academy, there are four handsome boys everyone admires.
These four share a single, specific "preference."
—Tall girls.
However, tall women make up only about 0.1 to 1% of the Japanese female population. They rarely encounter their ideal partner.
Then one day, a transfer student arrives at the academy.
Tall, with a stunning physique. She is the exact ideal they have been searching for.
Meanwhile, a petite girl who has been aggressively pursuing the four boys finds herself completely ignored, no matter how much she appeals to them.
Eventually realizing that all their eyes are fixed on the transfer student, she begins to view the protagonist as an enemy.
Discovered by the four princes, the tall transfer student...
—The four-way doting begins.
