Can a poem save your life?

Words are powerful. Insults and rumors can derail a career; a bit of encouragement can give someone the strength to pursue their dreams. When a high school boy skipping class to sketch shoe designs and a taciturn woman drinking a morning beer meet in a Tokyo park, they say little, but the woman bids farewell with an ancient tanka poem. Will the boy figure out the poem's meaning and its corresponding response before it's too late?
