Other similar RPs, though possibly not directly related, are:
- Win the Prince’s Heart by Rhiannon
- Win the Prince’s Heart SPECIAL EDITION by cheetmeet and Rhiannon
- Win the Princesses Heart by Creative_Fish
- Rulers by Caroline_G_Shaffer
- Secrets RP by evergreen
Though some of these are not directly related (some are inspired by Real Soul Mates, or by the original Win the Prince’s Heart), most agree that they can all be traced back to GGRC.
