Once upon a time Raju in a tuition class saw a girl in a red t-shirt. That just stuck.

Six years later Raju bribed a friend with Sharjah Shake to see her and tell her Jil.
Its Stuck.

Sharjah Shake - It is that summer banana shake that rocked in Kerala. No clue about its origin but its made of bananas and crushed semi-solid frozen milk sometimes with a twist of boost or chocolate added.
