A story of two people who have been afraid to commit, scared to fall in love yet unwilling to let go. At a very young age, Tanya Preston becomes an orphan when both her parents are killed in a car accident, leaving her under the care of her sickly aunt who soon dies of heart failure. Aidan Campbell is afraid of commitment; he hates responsibilities and is only interested in having strings of short-term, non-serious relationships until an old lady who is about to die asks him to look after her eleven-year-old niece when she's gone. Soon Aidan is left with no other choice but to grant his neighbor's dying wish: to act as Tanya's guardian, never knowing that his decision will change both his and the young girl's lives forever.
