By chance, I met my classmate, Ria, at my favorite coffee shop. At the time, she had a reserved demeanor, but it seemed like she had softened up quite a bit. We started reminiscing about the old days, and since we both worked nearby, we started eating at the coffee shop often. But I have a fiancé. And I couldn't tell Ria about it. It would be convenient to say that there was no trigger... but Ria saw me with my fiancé.
