Himekoi

Yoshikuni and Okada were classmates, but Okada's transfer to a different school led to their separation. Years later, they cross paths again, and Okada is struck by Yoshikuni's changed demeanor, despite not recognizing him at first. As Okada begins to notice Yoshikuni's differing treatment of him, he starts to realize his true feelings for his former classmate. Their secret romance blossoms delicately, much like the fleeting beauty of cherry blossoms.
