Kirai de Isasete: Asanaga-sensei to Yanagi-sensei

Elementary school teachers Asanaga, an alpha, and Yanagi, an omega, are more than friends but not quite lovers. And while their relationship began with Asanaga’s fervent, one-sided pursuit, Yanagi has found himself warming to his sincere—albeit pushy—affections. But even if he wishes he could stand on equal footing with Asanaga and reciprocate his feelings more openly, insecurity about his omega nature and traumatic past hold him back. In spite of it all, Asanaga is determined to make Yanagi his and show him just how wonderful true love can be!
