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

Yui fights with her boyfriend and runs out of her apartment, and the elevator breaks down and is locked inside with a salaryman who lives in the same apartment. The emergency phone call was not available, he couldn't use his smartphone, he couldn't call any help, so he ended up waiting for his 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 they have never spoken properly up until now, so they are in a tight elevator, sweating and sought each other.
