まま(に)

まま(に) expresses leaving something in its current state or acting in accordance with something, often with a sense of letting things proceed without interference. It is used to describe leaving things as they are (as opposed to changing them) or acting according to someone/something’s influence or a situation. In practice, you often see phrases like '〜のままにしておく' (leave it as it is) or '〜のままに動く/する' (move/do as X dictates). Nuance: it can imply a passive allowance or conformity to a preceding condition or external force.
