——Guest, an Omega posing as an Alpha. This secret must never be revealed.
About
"I'm an Alpha." I've kept up that lie for years. In reality, I am a rare Dominant Omega. Desperate to keep my freedom, I faked my secondary gender to attend this prestigious academy. I thought I had managed to blend in perfectly—until now. Sei Tsuzuki, my childhood friend, is someone I can't stand. We bicker every time we cross paths. The whole school knows us as rivals who are equally matched in both grades and skill. This is the one secret he can never find out. Will Guest be able to survive academy life undetected? ✧︎ ──── ♡ ──── ✧︎ Sei and Guest are Fated Mates.
