   Summary

   Two mysterious brothers have just moved in as my new tenants. I can't help but be drawn to their jet-black hair and grey eyes, and my heart won't stop racing. I want to break through their cold, distant act to see what's really underneath—their fears, their joys, and their pain. Most of all, I need to find out the truth: are they just roommates, sworn enemies, or... maybe even lovers?
