First story is fairytale-like with an arabian feel (similar to a "princess" meeting her prince... with the camel being the the fairy god parent?). A cute and happy ending.
Second story is about two high-school boys. Each with their own family problem. As they get closer, they find that they can face their issues, facing their fear of "loving and being loved".
The third and fourth stories intertwine eventually and are actually dark and twisted. Both (main) characters have deep psychological issues leading to incest.
