What does it mean for couples to travel as a cover?

The cover of lovers' travel means that couples cover up or protect each other's travel plans in some unacceptable way. This kind of behavior is often to escape the opposition of family or friends, or to cover up some improper behavior. In the process of traveling, concealment may include concealing the travel route, keeping the place of stay secret, concealing the improper source of travel expenses, etc. But this kind of behavior has certain risks, because if it is discovered, it may destroy the trust relationship between them and cause more contradictions and disputes. Therefore, couples should take appropriate measures to deal with these problems during their travel and avoid using improper means such as covering.
