A free mod for Stardew Valley, by bwdy.
You have just returned home after a long trip and are exhausted. You want to rest for a few hours, but your friend is busy and can't come to the phone. You know that if you call him he will just be annoyed. So you decide to send a quick message instead. You ask him to join you for a sleepover.
Now you can spend the night with friends and get some rest. But you need to be careful not to disturb your friend or cause trouble. If a compatible NPC is sleeping, you can activate them to ask about spending the night.
