Oblivious by Heather Mar-Gerrison

Kurt has finally gotten away from his very loving, very protective, very nosey family and is enjoying his long awaited time at university.
His roommate, Sebastian, very quickly becomes his best friend and they’re rubbing along very nicely thanks very much until Sebastian has a guy over and Kurt walks in on them.
Suddenly Kurt’s life is turned upside down. Why does he react the way he does? Is he homophobic? But no – he can’t be. His best friend back home’s gay – and so is his twin brother – so why does he feel nauseous every time he sees Sebastian kissing other guys?
