The promise I made with my childhood friend: "If you're not married by 30, I'll marry you." More than 10 years have passed and I still can't let it go. But she is already married with children… We reunite in my hometown after a long time. Faced with our vastly different current situations, I try to leave with the past buried in my heart, but she stops me. "At least… just a kiss…" The feelings suppressed for over 10 years accelerate in an instant. And it doesn't end with just a kiss… My childhood friend is also breathing heavily… Our first and last sex… Thinking that, the excitement is unbearable, and we greedily devour each other's bodies in passionate intercourse!
