Kimi ni Naifu
A story that is deeper than the stab wounds. Read it carefully. A model who is so beautiful ...a manager who is so devoted...a crime that is so.... Pay attention to pages 11, 17 and 26 and the end. Close attention. Especially to metaphors (apple/knife; going crazy; finish me off; bandages that look like flowing blood; etc) If the "You" is the model, ask who holds the knife.

Awa ni mo Narenai Koi Nara ba
First and last stories have huge ick factor (though the last one has comedy and better story). First one just gross. The "Kami-sama" stories are more serious, with tragedy, with unrequited love, and a guy with soul-crossing facilitation ability.
