Yes, I remember I really liked this one myself. This is the one where one guy is shorter than the other and he's all obsessed about growing taller, to the point where the other guy begins to doubt if they have a real relationship? If I'm right, the story matures past this seemingly silly beginning and deepens the boys' relationship as they grow up.
I've never been a fan of huge time jumps in my fiction, but because the Japanese do that a lot, I've come to best like the stories that show real growth through the passage of time. Cool/Uncool is one such story.
