みなと商事コインランドリー [Minato Shōji Coin Laundry] Series by Sawa Kanzume, Yuzu Tsubaki, Carolina Hernandez, Kei Coffman

Akira Minato inherits an old, rundown laundromat from his grandfather, and takes the opportunity to quit his corporate job. Instead of the laidback life he was expecting, his days are spent in a flustered panic when high school hottie, Shintaro Katsuki, ambles into his life...

Akira Minato, an ex-office worker who now owns a shabby laundromat, doesn’t know what to do when high school hottie Shintarou Katsuki professes his feelings for him. Still troubled over a past love that he never came to terms with, Akira wants to refuse-but he can’t quite bring himself to deny Shintarou’s straightforward passion. Meanwhile, Shintarou’s classmate, Asuka Hanabusa, decides to meddle in their affairs…

“I won’t stop loving you.” Akira is unsure of his feelings for Shin after receiving such passionate advances from the boy. But after watching Shin’s performance at the sports festival, he understands the deep affection he has for Shin is not romantic love. That's when Akira runs into his high school teacher and former crush, Sakuma...!

Akira Minato has maintained a friendship with high schooler Shin, avoiding reciprocating the boy’s passionate advances toward him. But one day, Akira unintentionally breaks a promise he made to Shin, hurting him deeply. Shin then stops visiting the laundromat, upsetting Akira. How will their relationship ever recover!?
