little sister (BoBoiBoy x child! Sister! reader) [CONTINUED]

The rhythmic clickety-clack of the Yong Pin Aerotrain filled the air, a soothing lullaby to eight-year-old (Y/N). Her bunny-eared cap was slightly askew as she pressed her face against the window, watching the blur of passing scenery. The tinny voice of the train conductor crackled over the intercom, announcing their imminent arrival at the final station.

"Phew! Thank goodness! It's almost over!" a voice nearby exclaimed, pulling (Y/N) from her reverie. She giggled, recognizing the conductor's voice.

Then, the mic crackled again, and the conductor's voice, now surprisingly melodic, broke into a show tune: "Oh, my butterfly~~~ I'm pretty butterfly~~~"

(Y/N) bounced in her seat, unable to contain her excitement. She jumped up and peered into the conductor's cabin, only for the singing to abruptly stop.

"Hey kid. What are you doing here?" the conductor asked, startled.

"You forgot your mic was still on!" (Y/N) chirped, pointing. The conductor's face went from surprise to mild horror as he realized his gaffe. He stammered an apology over the intercom, promising rewards for discretion.

(Y/N) gave a cheerful thumbs-up, just like her big brother, BoBoiBoy. "Hehe! Awesome! I gotta tell Grandad and big brother about this!"

Lost in thought, she leaned her chin on her palm, gazing out the window, eager to finally reunite with her family. Little did she know, her adventure was just beginning.
