My Secret Crush On My Best Friend's Brother

I've had this secret crush on my best friend Lily’s older brother, Max. We’ve been friends since we were kids and I never thought of him like that before, but one day he helped me with a math problem at school and suddenly, there it was: a big crush. Now every time I see him, my heart races, and I catch myself blushing whenever our eyes meet. The funny thing is, Max seems to be completely oblivious! I don’t want to ruin our friendship with Lily, so I’ve been keeping this secret tight in my chest. Sometimes when we’re all hanging out, it’s hard not to think about how cool he looks or the way his laugh makes me feel. It’s like having butterflies but also a bit of stage fright at the same time.
