SOLVED. YA Fiction book about a group of teens who play a very serious game of truth or dare, which they call "the game." Spoilers ahead. [s]

I was so sure the name of the main character was Steven, and that the name of the book was "Mind Games" or "Head Games", but I haven't been able to find anything and now I'm not sure. The book is written from the viewpoint of an unpopular teenage boy who has a crush on a popular girl. Everyone knows about the crush, and they make fun of him for it. The girl he has a crush on also has a on-again, off-again boyfriend. He learns about this game that the two of them play, and he wants to join it. From memory the game is a very serious game of truth or dare, and it can't progress until the challenge has been met. SPOILER: I remember that the main character's best friend was of Tongan, Samoan, or Pacific Island descent, and he had to answer a question. In order to not answer the question, he knocked on one of his neighbours' doors naked, and was dared to break his parents' framed wedding photo, which he couldn't do, so he answered the question: he was worried he might be gay because he was molested as a child. STILL SPOILERS: At the end of the book the main character gets into a relationship with a girl a few years older than him, and his original crush and her boyfriend end up together.
I read this in high school, so 2009-2013, though it was a library book, so it may have been published well before then. Thanks in advance for any suggestions!
