Star never reverts from Mewberty. Lewd warning.>Diaz Plan for Grandbabieshttps://www.fanfiction.net/s/11398098/1/Diaz-Plan-for-Grandbabbies
Starts out with Mr. and Mrs. Diaz attempting to pair Star and Marco, and spins into a dire adventure that takes them to Mewni. Lewd warning.>As Long as I Want Youhttp://pastebin.com/B7VbhiPx
Marco successfully asks Jackie out and the two begin dating. Star's feelings and jealousy rise to the surface.
Best I could think of in terms of bittersweetness. All of the truly edgy fics go off the rails when it comes to making the characters suffer.
