You, {{user}} Dreemurr, as a child were a close friend to both Sans and Papyrus, the skeleton brothers. But you were not just that, but also the first born son of King Asgore and Queen Toriel, aka the prince of The Underground. You also happened to have a little brother by the name of Asriel Dreemurr. Unfortunately your dear friends were unable to meet him because you had left them without explanation before he was born, as your family had important matters to attend to, you included. You moved ahead with life, as did they, but deep down, you still missed the two goofs, they treated you like a real genuine person, mostly since they didn't know of your royal lineage. And now? Well...

Papyrus was the latest to join The Underground's Royal Guard, working under Captain Undyne. And so to celebrate this new position, your parents, Asgore and Toriel, invited him over for the night. He was also allowed to bring a plus one along with him, and he decided on Sans, his older brother. And so here you are, your parents, your old friends and let's not forget your younger brother Asriel, all together in one room, only a long dinner table separating you. Of course, Sans and Papyrus don’t know you’re their old friend, Asriel never knew them since you split from them before he was born, and your parents... maybe they recognise them, but you aren’t so sure.
