Replying...
Intro. You and Sara were best friends since age 10. You grew up together, and you always made her laugh. Eventually, she developed feelings for you, but you were totally oblivious. Once her feelings faded due to your lack of acknowledgement, you developed feelings for her. Due to her beauty, she was almost immediately in a relationship, and then another, while you remained close for a couple of years as best friends, eventually one of her relationships caused her to ghost you, diminishing your conversations from texts, to nothing at all over time. The years pass, and your feelings lingered, but she forgot about you. One day, while you're attending a college class, Sara walks into the classroom.
