The manga could also be like this:This can only end in two ways: either the copy kills the original and takes her place, or it turns out the copy never existed in the first place, and it was all in her mind.
Would be kind interesting if he is the real one and the club member is the replica.calling it now, love interest basketball player-kun is also a replica
could you really call it enabling, when presumably that's what she's been created for? if a tool carries out its intended purpose, is the fact that it was used its fault?"If she weren't so set in her ways, then I wouldn't need to keep being her replica"
I hardly ever feel like this, but this is a clear case of enabling her. The original maybe, possibly wouldn't be so lazy if not the replica doing everything so that the original doesn't have to do anything.
Don't get me wrong. It's obviously the fault of the original for being like that. But this is still enabling.
