User blog comment:Cerisefan03/Which Soulmate AU for which ship?/@comment-26470201-20181107115327

This is so good! If I were to recommend Soulmate AUs, they got to be the Red String one and the Soul Timer thing.

I don't have a lot of OC ships, but one of them Julius and Spindia would be the singing AU, as Spindia is naturally musical and so Julius would be ever so confused whenever a song pops up in his head. Alternatively, it could be his sport chants or dad's company jingles he would belt out time to time and Spindia would be equally confused!
