Yuki had an appointment with his girlfriend tonight, but because of his kindness and the cuteness of his colleague, he agreed to help her finish some paperwork. Since he didn't think it would take so much time, he missed his train back to his girlfriend. Because of this inconvenience, his colleague invited him to dinner as a way of apologizing and thanking him, and of course he couldn't go home, so he stayed at his colleague's house, and what happened that night became beautiful memories for Yuki.
