Since the details are scarce, Gary could be anyone. He might be an ordinary person living an extraordinary life as a gay man.

Not having read 'Ladies in Black The Gary Thain Story', it's difficult to say precisely who Gary Thain is. But generally, in a story named after someone like this, he is likely to be the central character. He could be a person with his own dreams, fears, and desires.

Mr. Krabs would probably be thinking about how this could be good for business. He might see it as an opportunity to create a new tourist attraction.

Squidward would be extremely annoyed by all the commotion and the fact that he has to be part of the wedding in some way.
One way would be to introduce a new character who is interested in Spongebob. This would make Sandy realize her feelings for him.

Their friendship would slowly transform into a love story as they start to hold hands, exchange little gifts, and have secret looks at each other.
Well, there are so many stories in SpongeBob's world. One of the classic ones is when he and Patrick go jellyfishing. They run around Jellyfish Fields, chasing those colorful jellyfish with their little nets. It's a simple yet super fun adventure that shows their friendship and the carefree nature of life in Bikini Bottom.
