Frisk x Reader : The Day We Fell In

The truth

Your pov

"Well,Chara was the first fallen human,and he died from an illness that wasn't cured in time. My son,who also died on the same day,got killed by  the humans." Toriel told us the story. Frisk seemed sad. I had a blank face. "Well,Toriel,can we stay here?" I asked. Frisk nodded. "Sure children,I will be sure to take care of you." Toriel smiled. The Chara ghost thingy was behind me. I looked behind me and he sheepishly smiled. First the monster tried to kill me,now he's the 'oh so innocent' boy?! What the heck!
I went in the small little cabin,it looked pretty decent. Toriel guided me and Frisk to our new bedroom. Guess we're sharing!
~Time skip~
It was night,and Frisk was in bed while I was on the floor. I remembered that I had my phone,and luckily I also had my headphones and charger. Bad thing,all of my games were online games. I can't get internet down here. Anyway,I decided to listen to the radio,and one of my favorite songs came on (sorry if you don't like the song). It was No from Megan Trainor (IDK how to spell her last name lol). I started to mouth lip the song.
I think it's so cute,and I think it's so sweet,that you let your friends encourage you to try to talk to me.
Then I actually started to sing.
Down to the ow to the no no no.
My name is no,my sign is no,my number is no,you need to let it go,you need to let it go,need to let it go,Down to the ow to the no no no.

I was hearing Y/n sing,and she thinks I'm asleep. She has a beautiful voice. Angelic, actually. I wanted to tell her that she had an amazing voice,but,I'm too shy to tell her...
First you gonna say you ain't runnin' game,thinkin' I'm believing every word. Call me beautiful,so original, sayin' that I'm not like other girls.
I turned around to see Y/n still singing. Hearing her beautiful voice fills me with determination and....love?
I was in my zone before you came along,now I'm thinking maybe you should go. Blah blah blah,I be like down to the ow to the no no no.
I was blushing at the thought of me...loving...her... I think I'll step up my determination to....never mind..
All my ladies listen up,if that boy ain't givin' up,lick yo lips and swing yo hips,girl all ya gotta say is...
Then I got up from the bed. Y/n stopped singing and looked at me.
"Youhaveabeautifulvoicepleasedon'tstopsinging!" I managed to say in one word while blushing. "Maybe next time," and then Y/n winked at me.
