Ever since that day, he’s been searching for the “cool big brother” who changed his life. Years later, Hotaru has grown into a full-fledged yankee himself. One day, he steps in to rescue a timid office worker from some punks—only to notice a familiar mole on the man’s face. But when he takes a closer look at the man’s face he spots a mole in the exact same place as that yankee brother he admired all those years ago! Turns out, Hotaru’s once-cool savior, Kyoshiro, has become a gentle, fluffy office worker with a secret love for cute, fancy goods!
