Scar's parents died in a fire, Taru's house was also caught in the same fire.
Taru was saved from the fire but along with her brothers but the rest of her family couldn't be saved. Taru met Scar 5 years later after the incident.
Even though Scar doesn't like company, he lets Taru follow him around.
Taru likes to laugh about Scar's mistakes
Taru never says "sorry" directly.
Taru likes to mess with Scar and it makes her happy and giggly when she "hits the spot". Scar tends to get very angry after that but never hurts Taru in any way.
