A day before my 40th birthday, it dawns on me that my most accomplished trait is that I've been working in the same office for 18 years. Struggling with an angry customer during an event for a new department, a charismatic salesman comes to the rescue; twelve years younger Kohei Nakajima. On the way home, tears fall as anxiety kicks in, realizing I had turned 40 years old. Suddenly out of nowhere, Kohei appears and confesses his love for me?! I had lost hope... At this age, is it too late to welcome spring into my life?
