This is just my opinion about how the undertale fam. (Sans, Pap, Asgore, Toriel, Frisk, Chara, Mettaton, Alphys, Undyne, Flowey and Asriel, and my OC Ally (the skele-bros sis)) would react to the different ships, and pls remember that Undertale belongs to the amazing Toby Fox and don't hate me just bc I like Undertale (not assuming you would but I know SOME ppl that bully me bc of it) so without further ado, lets begin. Also, this idea was inspired by OGB (go check out his story :Sans reacts to Undertale Ships)
