When Ritsu was in high school, he fell in love with a boy who broke his heart, changing his view of love forever. Now a jaded adult, Ritsu has just transferred to the Marukawa Shoten company in hopes of publishing literature, only to be told that he'll be working in the shoujo manga division instead. What's worse, his boss is brash, rude and seems to have an interest in him! However, the biggest surprise is yet to come for Ritsu, as he soon discovers that his boss is none other than his lover of his past!
I Can't Even Breathe Without You is very much like one of the couples in Onodera. These are BL manga focused on managaka who rely completely on someone to take care of them, the level of dependency being extreme in both cases. Not only that but the daily routine of manga production is an important theme with deadlines always around the corner and overwork.
