Here a fanfic idea: SpongeBob and Squidward secretly dating about three months. At the Christmas party Sandy bring her new invention - mistletoe that makes a barrier if lovers stand under it and they cannt leave until kiss. So thats obvious what will happen next (that can be an accident or SpongeBob can bring Squidward under it on purpose).
This was longer than expected but I hope you enjoy it anyway! I’m worried I might’ve made it a bit too sappy but here you go. Thanks for the prompt!
