On the way home from the drinking party, her best friend Fumika, who missed the last train, ended up staying at the house where my girlfriend and I live together. Drunk Fumika tempted me while my girlfriend was sleeping next to me. I couldn't resist the temptation... The next day, unaware of everything, my girlfriend went on a four-day trip with her family. Even though I knew it was wrong... The two of us left behind... A record of the two of us indulging for four days.
