Gaster! Sans x Reader ㅣ Complicated love

It's been a year ever since the monsters were freed from the underground. When Frisk came back, you were overjoyed to see them. They let you become friends with the monsters and you realised that you had developed feelings for 'someone' (insert lenny face here) but you were too tsundere to tell him. How will this conclude? Find out when I can write xD
