There are some things you just can't take back. No matter how many times you reset. After breaking free of Chara's grip, Frisk decides to do one final reset before defeating Sans or proceeding to the throne room. But some memories last longer than others, and broken trust isn't easy to repair. Female, aged-up Frisk. Starts out canon and then diverges. Eventual Sans x Frisk. Undertale was created by Toby Fox. I do not own Undertale, nor any of the characters. Some violent action scenes. Cover art is by amazing artists at http://www.zerochan.net/Undertale,Fanart and http://www.zerochan.net/Chara+(Undertale),Fanart
