haiiii

I'm looking for an anthology series written by one author. There was only one chapter TLed, and although the only genre listed was BL, it was a GL(ish) oneshot.
It's about a woman in her late 20s who greets a woman in her 50s in her garden because she thinks the older woman is cool. In the last part, she tries to strike up a conversation with the woman by saying her gardens pretty, and the older woman calls her pretty back. Any help would be appreciated for this, thanks!
