Ridgeside Rival Hearts - Sam and Alissa is a fan-made application for Stardew Valley. The app contains events for Sam and Alissa from Ridgeside Village, with a romantic route and a platonic route, with an optional married version for the romantic route complete with schedules and dialogue, and an optional family version that gives them a toddler!

The mod contains a pack for the Multiple Spouse Dialogs if you are using the Multiple Spouses and are married to both Sam and Alissa.

Platonic Partners and Friendships is recommended if you are not using the polyamory version.
