This is not a pedophilia, sure the uke looks like a kid but no (he is just drawn to have a bby face). It will became a Pedophilia if the uke is underage and the seme fell in love with the uke because he looks like a child but in this case it’s not the same.
I hate love triangles but this is the only exception
I think it's more of a poly relationship than a love triangle
Cause in love triangles the two wouldn't want to share him but in this they did so it's probably more poly
