Meh, even if he doesn't show them on screen, I think DPC should make an explanation what happened to the other characters. It's going to be retarded if he goes like "All the women never loved again because MC's dick brainwashed them".
Like for example the dev of My Sister, My Roommate showed what happened to the LI's who you didn't pick and he showed them as they developed relationships with other characters. People weren't mad about it.
In Chasing Sunsets if you pick Mallory and you see Jaye ending up with Tara, are you really going to be mad about it?
