”Mayonaka Heart Tune” is a youthful romantic comedy centered on the theme of ”voice,” where dreams and love intersect. The story begins with second-year high school student Yamabuki Arisu, who continues to search for the radio broadcaster ”Apollo” who once saved him. The premise of holding onto feelings based solely on a ”voice,” without knowing a face or real name, immediately draws readers in. The story gains significant momentum the moment he discovers a clue within the broadcasting club of the high school he has entered.

The broadcasting club consists of four girls, all of whom dream of jobs related to the ”voice.” While they have different goals—singer, voice actress, VTuber, and announcer—they share a strong desire to ”deliver something to someone through their voice.” Arisu resolves to support their dreams to the fullest in order to uncover Apollo's true identity, but the charm of this work lies in the feelings that sprout beyond a mere cooperative relationship during that process. The mystery element of who Apollo is and the growth drama of each heroine are exquisitely intertwined, increasing the depth of the story as you read further.

A unique point of this work is that it places ”fandom activities (oshi-katsu)” at the center of the story. Arisu is not just a protagonist who falls in love; he involves himself from a ”producer-like” standpoint to make the heroines' dreams come true. This portrayal is modern yet very passionate, making readers strongly feel the ”preciousness of supporting someone.” Furthermore, the heroines' efforts toward their dreams are realistic, as not only their successes but also their conflicts and anxieties are firmly depicted, making them easy to empathize with and full of charm that makes you want to cheer for them.

As symbolized by the phrase ”Heart Tune” in the title, this work carefully depicts moments when hearts resonate through voices. A past where one was saved by someone whose face they didn't know, an earnest wish to hear that voice once more, and the expectation and confusion of thinking they might be right in front of them—such delicate emotional fluctuations give the story a deep resonance. Despite being a romantic comedy, the fact that it contains a certain poignancy alongside its brightness is very impressive.

”Mayonaka Heart Tune” is a work that allows you to not only enjoy the romantic developments with the cute heroines but also reconsider the meaning of ”pursuing a dream” and ”supporting someone.” While the mystery of Apollo's identity pulls the story forward, the emotional changes and growth of the characters are depicted even more carefully, leaving a warm yet slightly poignant afterglow after reading. As a piece filled with all the brilliance and anxiety of youth, I felt it is a work that will resonate with many people's hearts.
