In the main story, your can see that MC has changed and grew his hair out, as his lover, let him grow into his own person and is essentially the better choice. However, when the MC is with the other dude, you can see that he has not changed as I feel like the black haired dude would be more controlling as can be seen in the first story, though idk but i feel like this has meaning in it, despite being in Alt Universes.
