the string finds its way

Aabha was a six year old girl when she met her then-best friend, Maanav, in a big, scary looking school. Maanav had a strong affinity for her, but she had to leave that school the same year as her father couldn't afford to pay the fees. Now that she's 16, Maanav pops in without any sign. She gets thrilled and considers this as a sign. But the thing is...he doesn't remember her at all.
