This was really nice. Ch1) A boy gets paired up with a large, gloomy, disheveled looking guy for a project and they become friends when the boy realizes that there's more to him than his looks. He gives him a makeover but regrets it when the big guy gets a lot of attention from the ladies. Ch2) Two boys are friends. One of them is cursed with horrible luck, and the other takes care of him the best he can, but one day he realizes that his friend's bad luck might be caused by him. Ch3) Two, comically over-mature preschool kids play matchmakers to their teachers. Ch4) The kids as teenagers reminiscing about the teachers. There's a hint that the blonde boy likes the other boy but there's no resolution at all. If this chapter didn't feel so incomplete I'd give this more stars.
