Your point of view
I can't believe he just left. I feel empty inside and I feel like my heart has stopped. I ran back to the shack in tears. I ran past Dipper, Mabel and Wendy and ran straight to my room. I slammed the door and locked it so no one could come in. I fell onto my bed and cried into my pillow. I heard knocking on my door, but I ignored it.
"Y/n, its Mabel, open the door. I wanna help." She said muffled through the door. I sighed and opened the door slowly. I wiped my eyes and took a deep breath in. I stepped aside and let her come in, she sat on my bed as I closed the door. She then pet the spot next to her for me to sit down. I walked over and sat down as she embraced me in a hug.
"Now tell me what's up." She smiled.
"I-I think I like someone." I said through tears.
"Spill the beans! Did he reject you!? I'll kill him!" She shouted.
"No Mabel he left." I sighed.
"Oh my goodness. Don't worry. I know someone who does like you and probably won't leave for a while. I just wish he would hurry up and confess." She muttered the last bit.

Bills point of view
I watched y/n from the mindscape as she cried. I had really hurt her, more that I would have if I stayed. I wanted to hug her and tell her I was sorry and never ever let her go. I wanted to hold her close so then I could feel complete again. I want to stay by her side until the end of time. I didn't want to leave her, but why would a human want to be with a demon. She should be with another human. Not with someone like me. I wouldn't want to get her in trouble.

Your point of view
I don't care about anyone other than him. I just want him to come back.
