A love line that curves as an arc represents fluctuation of emotion and relationships.

An individual with this kind of love line values his or her relationships very much, yet is often burdened by relationships and friends.

Clandestine love affairs with married parties could very possible happen in his or her life.
People with curved, arc-shaped love lines usually also have ‘Immigration Lines’.
They may move to a place far away from home, or immigrate to another country.
They may also marry to a foreigner.

Otherwise, they could be adopted or raised by people other than their own parents.
