Becoming Bill's Bride (Mabel x Bill)

(Any picture in this story including the cover is not mine and belongs to the artist who created it. Gravity falls along with its characters are not mine either!!!!! They belong to the geniuses who thought and created it:) Also thank you for reading.

It has been a month since Mabel and Dipper have returned to gravity falls. They are now 17 almost 18 in a few months and everything is perfect. Mabel is enjoying her life in gravity falls with all of her friends and of course her twin bro! And as for Dipper, he is enjoying time with his twin sister and Grunkle Ford who he tends to go on adventures with. Although, that all ends one night when they find out that their parents had died. Of course, Mabel was sad but she handled it differently, she smiled, she laughed, she hid her emotions, and she distracted herself. She did that for weeks and avoided any talk about her parents or about her brother who looked too much like their father to bear. So for weeks, she stayed away from him before finally realizing that this wasn't the right way to go through with things. So she decided to talk to her twin but when she gets there he is......laying there...pills surrounding him.....The next thing Mabel knew she was in a hospital where the doctors told her he was brain dead and there was nothing they could do but like hell, Mabel was going to give up on him. So she summoned the only person that could save him....Bill. What will the deal be? What will he ask of her? Or will he even be able to do anything at all? And what will this develop to?
