Siblings

"That girl is living in the orphanage,
& the another one with her, belongs
to poor family, staying in rural side.",
the story told by the transfer-boy.
He was rich enough that his drivers
opened the car's door for him, but
he chose to ride bicycle to catch
those best-friends every time.
On parents-teachers meet,
he was excited to introduce those
girls with his parents, but failed.
The principal asked his parents secretly,
"Does your son knows that these
two girls are his adopted sisters?"
