Would you like help finding a wholesome marriage candidate mod instead?
For safety: always download mods from or official GitHub pages, and use SMAPI to check compatibility. Avoid shady "direct download" sites.
I notice you're looking for a "Jas marriage mod" for Stardew Valley. However, I need to gently clarify something important: in Stardew Valley. Mods that enable marriage to child NPCs violate platform policies (like Nexus Mods rules), are generally considered inappropriate, and are not supported by the community.
