You where always shy even before you fell in the underground. You didn't mean to fall you just wanted to look but you tripped. When you fell you where scared, you ended up meting a skeleton named sans. You have only known him a few days but he was nice to you. When you first met him you didn't really talk because you where shy and didn't want to say something stupid, he caught on to this.
(Now for the story)
You just got out of bed and went to grab your clothes, you got your clothing and got dressed. You had stayed the night at the skelly bros house. You meet Sans downstairs he asked you if you wanted to go to Grillbeys and you said yes.
(Time skip to Grillbeys)
"Hey (Y/N) what do you want" Sans asked and you said you wanted Burger/Fries. You and Sans ate in silence it wasn't awkward but comfortable Sans knew that you where shy and didn't really like to talk much so he didn't talk much around you since it would make you feel uncomfortable.

After that you went to waterfall you where amazed by the Echo flowers and star stones. All of the sudden you felt like you where being watch "w-who's th-there" you tried to sound brave but it didn't work. You could only think of one thing to do.....you ran, there was nothing on you mind but to run. You ran for about 5 minutes until you bumped into someone you had tears in your eyes from fear you didn't bother to look up you where frozen in fear. You held your face you where shaking you started to cry "d-don't h-hurt me" tears where streaming down your face. You felt a bony hand on your shoulder when you realized who it was you jumped into his arms and hugged tightly "what happened (Y/N)" Sans tried to comfort you "I-I think s-someone w-was watching m-me" the tears where falling like waterfalls Sans stopped hugging you and pulled away he wiped away the tears "Hey kiddo don't worry I wont let anyone hurt you" Sans said and picked you up "y-you p-promise Sans" you asked "I promise kiddo" he said and kissed you on the head.
