Underfell! Sans(Cherry) and Papyrus(Boss) had gotten in serious trouble for almost shattering a innocent monster's soul. But Undertale! Sans(Sans) has a better idea than just sending Underfell Sans to Error!Sans(Error) in his private jail. Instead, Undertale! Sans decides to send Cherry to live with Underswap! Sans(Blueberry) and Papyrus(Orange) in Underswap. Can Cherry survive Underswap without killing anyone? Or will he fail and be sent to Error's prison in Errortale? And what happens when Cherry starts to grow feelings for the adorable person that is Blueberry?

Red has a goal. To get Flowey to UnderSwap. But when Blue comes crashing through the portal and has to stay in Underfell till it's fixed, it's hard to say what will happen to them. Yeah I know, not the best description but don't know how else to put it. This is mature rated and I suggest you read with caution. Also, Undertale, Underfell, Underswap and all the characters in it do not belong to me. They belong to their rightful owners. The Artwork doesn't belong to me either, it belongs to freshoutofparsnips on tumblr. This is not my first fanfic but it's the first one I've posted online, so please, if you have any advice for me I will gladly accept it.
