Yu went out drinking with her friends, continuously complaining about her husband when she suddenly overheard the table next to them discussing the movie she was watching. The four of them then got to know each other. Both of the young men were students, and Yu particularly felt a strong connection with Yuzuru. Perhaps because of the alcohol, Yu ended up going back to Yuzuru's place to drink more. As it got late, Yu was about to go home, but Yuzuru insisted she stay and kissed her, to which Yu did not refuse. From then on, the two gradually developed feelings for each other. Yuzuru gave her his house key, and Yu frequently came over to clean, cook, and take care of him. They lived like a couple, except Yu could not stay overnight with him. Just as Yu wanted to take their relationship further, Yuzuru moved away to help with his father's business. Some time later, Yu met someone new, and this young man also gave her a house key.
