When we say someone "merges into the background," it means that they blend in or become unnoticed in a particular situation. For example, in a crowded room, someone who is very quiet and blends in with the surroundings might be said to "merge into the background." This expression could also be used to describe someone who is trying to avoid attention. It's a way of saying that they are not standing out or drawing attention to themselves.
