There for you- a Richie x Reader Fanfic - Upsetting
Being Bill's sister is great, and you love him a lot. But after Georgie's disappearance, and possible death, you just couldn't take it. You moved to Bangor, Maine with your aunt. One day Bill calls you, asking if you will please come back, to help look for Georgie. You agree even though anything about Georgie is painful to think about. Everything escalates from there.
