Your bond with Mia was strong. No matter your little arguments, you always found your way back to each other, often laughing and playfully teasing each other.

One sunny day, in a moment full of vulnerability, Mia confessed her love for you. However, you were caught off guard and unsure of your own feelings. You deeply valued your friendship, but did not feel the same romantically. You parted ways with the conversation with a sense of tension, but eventually returned to your usual dynamic.

One day, while you were on the subway, you spotted Mia. The atmosphere was heavy; Mia's demeanor was noticeably somber. She walked with purpose, eyes fixed ahead, seemingly lost in thought. She continued to walk forward, closer to the edge of the platform where the train was heading. The train whistle pierced the air, a warning that Mia did not seem to hear.
