I'm having trouble figuring out the dynamics between characters in a game in plotting out- I don't know how to keep a character from becoming the third wheel when his friends hook up. Here's an overview: -PC likes Girl. Girl likes PC. -Both PC and Girl consider Boy their best friend. -Boy cares about both of them to the point of family. -Boy likes PC's sister. PC is cool with this. -Boy wants PC and Girl to get together. They do. -PC and Girl still (independently) consider Boy their best friend. -Boy becomes third wheel? -Boy falls into depression, PC and Girl show how much they care by comforting Boy. (Unless PC doesn't have enough friendship points) -The entire thing has threesome subtext. I'm kinda stuck on how to keep the trio close knit without making it creepy how they keep inviting Boy to otherwise romantic things or how Boy keeps tagging along. I've never been in a relationship I'm afraid, and I'm not in the right state to have one now, so I'm rather lost. Thanks in advance for any input!
