“We'll always be friends!”

At the end of summer during his childhood, Hayato made a promise with his dear male friend. Seven years later, when he transferred to a high school in the city, he reunited with him… who had transformed into a delicate and beautiful girl!

Haruki, known as the “unattainable flower,” would innocently laugh and mischievously grin when alone with Hayato, trade lunches together in an empty classroom, and play games together at home… Yet, when treated and teased like a girl, she would blush deeply, suddenly becoming adorable.

Between the countryside and the city, boy and girl, matured hearts and bodies, amidst the changes that occurred during their time apart, remain unchanged feelings and promises…

A youth romantic comedy unfolds with a childhood friend who was thought to be a male friend!
