Anran kept a smile on her face all the way as she recounted her daughter first telling her she was lesbian.

"I noticed there was something going on when she was in junior high school," Anran said. "She was getting very intimate with girls while she treated boys as her buddies. But I didn't say anything."

It was not until her daughter had a job that Anran knew for sure. "One day by chance she confided to me that she liked girls and not boys, and then it all made sense."

Well educated herself, Anran wasn't surprised that her daughter was lesbian because she knew the existence of the homosexual group and knew that is was a normal social phenomenon.

"What surprised me was that she'd been dating a girl for years and I didn't have the faintest idea about that," Anran said, smiling.
