One is an old bachelor who has accomplished nothing in nearly forty years.
One is the chairman who was forced by his sister to have no way out but to transfer his shares.

An opportunity brings them back to their high school years, but they unexpectedly switch bodies, experience their own lives, and re-realize their own life values.
Intention: The ultimate value of life lies in awakening and thinking. Ability, not just survival. —Aristotle
