Locked by Heart

Heart lock is a padlock attached to a bridge by couples as symbol of their commitment to each other. The key is often thrown into nearby river to symbolize their unbreakable love.

However, even though the key is thrown away, a lock could be picked, or be removed. Even a bridge could be teared apart in time. To represent commitment better, I say we build a heart lock with our bare hands.

A couple shall build the heart lock together. Together, they'll see how their commitment form step by step. Every lock is paired with a key. Keep the key carefully because it's the key to each other's heart.

Interior mechanism pending.
