Hydrangea Cage
This is no where near romance. In fact everything about this just pisses me off. The Alpha is a outrageous, arrogant dick and emotional abuser who lies to himself constantly and the omega is a passive doormat. Yup. Pissed. Kaisei , The lil brother, is by far a better man than his older brother. His story is ongoing but good so far It's Secret Note.
Kanraku Alpha ~Enigma~ 4 verse
THIS IS COMPLETED. Dunno why it is marked otherwise but the ML and MC reach a Happy Sexy end. Alpha turned into an omega by one that is classed as a Enigma. It's really good definately worth re-reading
