So, first story is the rich/poor kids with one who is a "toy." Truth is, the rich guy loves the other one but of course doesn't have a CLUE how to express it. You figure it out in a flashback when the poor kid falls out of a tree and rich kid is worried. It's confirmed in ch 6.5 when rich kid says "I like you" in his sleep. He does keep saying throughout the first three ch that he's not letting poor kid go, like ever.
One story is a kid who watches a surfer and they end up together (surfer lives elsewhere but comes back to stay because of the kid).
Other story is the two childhood friends who hurt each other (stupidly) who end up company presidents and finally get together after being kidnapped.
