The elevator breaks down and we're alone... Sweaty and close-up sex

Yu runs away from her apartment after fighting with her boyfriend, and the elevator breaks down, and is locked inside with a salaryman who lives in the same apartment building. The emergency phone call was not available, my smartphone was out of range, so I couldn't call any help, so I ended up waiting for my help alone. Time passes by moment, but the two become anxious about the elevator, which has no response at all, and the two are both huddled together and touch each other, and the two, who have never spoken properly up until now, are in a small elevator, sweating and looking for each other.
