I'm rewriting the book, please read the Days with You [Rewritten]. That is the on going version. Though I won't delete this old version

Gray nearly dies in battle. Although Natsu saves his life, Gray is left severely handicapped and may never walk again. Now Gray despises Natsu, feeling weak and indebted, while the Dragon Slayer is confused with why he feels possessive over Gray. The team falls apart as both deal with intense feelings of regret, shame, desire, and both physical and emotional agony.
