Her uncle comes to her aid and exposes the alleged stalker as one of his tenants, which left Miko feeling self-conscious on her debut day.

Regardless of her mortification, Miko soon realizes that cohabiting with grown-ups is not as formidable as she first assumed, and she may even kindle romance at the boarding house.
