Hidden in the depths of the bustling city is an old street called "Bluestone Alley". At the end of the alley is a grocery store without a sign. It only opens late at night on every seventh day. What it sells is not merchandise, but "regret patches of life" - a precious memory in exchange for an opportunity to correct regrets.
Purpose: Regret is not a gap in life, but a pattern of growth. Accepting regret itself is the ultimate way to reconcile with life.
