You were about to wake up and saw you were on a bed. Chains were holding you back but not for long. You summon a Gaster Blaster and get you arm off the chains.

Sans pov.
I hurried towards y/n since I knew were they were at because I can sense they're magic. My idea was to teleport everyone towards the place including me. Once we were there we smashed the door down and entered. Well let's just say only me Papyrus and Gaster entered.

Your pov.
You stood up and walked towards the exit you were looking for. However someone grabbed you from behind. "Where do you think you're going my dear~" the voice and you realized it was Chara. "Chara let me go I can't do this and I want to see my friends" you said.
"Oh about that... I don't think they'll even get the chance to see you hahahahahahaha!!!" Chara said laughing like a crazy maniac. At the time you were trying to escape when suddenly. "Y/N, HEY SANS I FOUND THEM!!!" Papyrus said. Hearing him filled you with such happiness more then
anything else. You were happy to see everybody who came there to save you. "Guys I'm so happy to see you but who's that in the black clothes?" you asked. "Oh this is Gaster aka. my Dad." Sans responded. You tried to loosen but Chara still held you tight. Sans looked at Chara and they both have eachother the death glare. "Chara please let me go I don't even know why you're doing this and I think we had a fucking deal right ?!" you yelled asking. "I'm sorry my dear but I can't let you become different so that's why if I have to I'll kill whoever stands in my way!!!" Chara responded. "If it means that I have to die and come back changing to someone else for my friends ...   then I'd do it Chara. You have to understand that I can't abandon my friends and I also can't keep in this state so I really have get this thing done so please let me go" you said as Chara held you close to them. The were holding a knife ready to fight the others. "I  I  I ... NO I WONT STOP YOURE MINE AND MINE ALONE SO PLEASE go to your room my sweetheart." they said. They let you go and you looked at them. "You decide what's going to happen now. If you go with sans and the others then that's your choice but if you go with me I'll spare all of them." you looked at Chara in disbelief since it's not the first time they said this. And of course you chose the others since you didn't trust Chara anymore. "I'm sorry Chara I can't do this anymore so please just accept fate and let this be the last time we met, because I simply can't trust you." you said looking down with your back toward Chara and letting tears falling from you face. " I told you it's you choice to make and now I have to fight for you which means killing your friends and taking you by force!!" they said gripping to they're knife. The hallway was kinda big so you know what's gonna happen. Sans stepped up. And the both of you started "It's a beautiful day outside birds are singing flowers are blooming on days like these kids like you ... Should be burning in hell." You summoned many blades and Gaster blasters as well as sans and Gaster warning Chara at first. "Kid if you take just one step towards us we'll have to attack" Sans said warning Chara. And of course they stepped forward showing that they didn't care. "Welp sorry Y/n I guess we have no choice." Sans said. To which I put my hand on his shoulder and said "It's ok sans I'm ok with it since I don't trust them anyway" Sans looked at me first and then straight where we both said "Let's just get to the point"

Later after the battle Chara fled.

"I think that was too easy even for you sans" you said looking at sans. He looked at me said agreed but was very tired and also the house was kinda destroyed a little. Well you left the house and met everybody else and by now every single friends monster and human has come to see you and of course you were happy but there was one more thing left to do. You summoned a blade and told everybody what was going to happen and why. Then it started you hit you soul and after the soul broke you were still alive and it came back in a different form it was Golden this time. You were filled with all types of feelings and more you felt like your soul had a will to protect so you did so from then on. You were happy with all you're friends and family.

You were happy and felt great every time sans came to visit "So this is the happy ending I wanted" you said with a smile. One night you went to bed a usual but before you could fall asleep you heard a quite voice say "soon my darling soon we'll be together forever" before you entered dreamland.
