hello can someone help me i will quickly explain i am in chapter 2 where the main character Melmond and his friends find a portal the thing is there is a riddle here is the riddle question
A.R.M.A.:I can fill a space or a single mortal heart. If you try to distribute me, I will always leave. There are those who have me, but I cannot be shared For I only exist as one, I can never be matched
so I already tried to think of the answer but of course it was a failure so is it possible to give me either the answer or some hints :(
