My ex-girlfriend, Ichika, is now married and has become someone else's wife. I had a girlfriend too, so I thought I could bear this tight feeling in my chest... But when I found out that Ichika had the same feelings, I couldn't hold back my feelings... During the three days my girlfriend was away on a trip, we pursued each other more intensely and passionately than when we were together in the past. This is a forbidden record of just the two of us.
