My girlfriend's sister, who I live with, is the celebrity Takasho. One night, after the three of us had been drinking, she slept off all her drinks, and Takasho and I were the only ones awake. When we stopped talking and fell silent, we suddenly had a deep kiss! We hadn't seen each other since then, but when she was about to leave the house on a trip, I got a call from Takasho... This is a record of the four days I spent playing sad lovers with my girlfriend's sister during the limited time we had while she was away on a trip.
