"I want to grow up quicker, so I can date Minato-san." Minato Akira inherited his grandfather's coin laundry. And so, the middle-aged former corporate drone, Akira, peacefully ran the well-loved coin laundry. One day, a high-school student, Katsuki Shintaro, enters the coin laundry. Despite the difference in age, they quickly became friends. However, Shintaro suddenly finds out that Akira is gay. Adapted from the manga "Minato Shouji Coin Laundry" (みなと商事コインランドリー) by Tsubaki Yuzu (椿ゆず).
