i FELL for you - Kustard (classic x fell)

sans fixed a machine that brings him to another AU called underfell. he meets a skeleton who looks alot like him. they decide to go to grillbys for a drink, both ending up drunk and.. naked?! finally when they admit their feelings, it seems that everything was planned by the beast... Red and Blue (aka classic and fell) end up mad at eachother and Blue wants to end it all. should he use the "reset button" as nothing happened? or just deal with what happened and try to fix it?
