Suzume Tōjō is just three months away from turning forty and realizes 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!
