Suzume Tōjō is just three months away from turning forty and realises there’s so much he hasn’t done with his life! So, he makes a plan: create a private list of things he’s always wanted to do and check them off before turning the big four-oh. It’s a rather simple list, filled with goals that should be easy to accomplish, like a takoyaki party, enjoying a parfait out in a cafe, and spending his birthday with a lover. Except, that last one comes with a major problem - Tōjō hasn’t had a lover in ten years! But when Keishi Tanaka, Tōjō’s handsome junior at the company, discovers the secret list, he’s determined to help Tōjō check off every single item - starting with the “lover” part! A fun, sexy BL romp between an assertive junior colleague and a senior past his prime!
