Before you start the story remember  the following clauses.

Shiv and prachi are twins but Shiv is elder.

Shivachi is 12 years elder to that or Reha+Sahana+Arhaan.

Reha+Sahana+Arhaan are triplates.

This story would be mainly in Adi's pov.

Ranbir is the eldest among the kohli tolli.

Aryaan and Anurag are twins.

Pankti is the smallest.

Thank you
