It was my mother's best friend, Eriko, who brought my drunk mother home. Takeshi can't help but become curious about Eriko, who is even more beautiful and mellow in her sex appeal than he had heard. Although she was beautiful, she fell in love with a woman around the same age as her mother. Even though it's an unrequited love between a married man, I can't take my eyes off him. Eriko notices Takeshi's passionate gaze and approaches him with the intention of teasing him, but gradually becomes influenced by Takeshi's earnest feelings.
