Wails of the Bound: Beta

A new graduate, Sasabe, is assigned to Utou, who works for a major advertising agency and takes good care of his subordinates. Even though the newcomer is cheeky, overly ambitious, and shows a bad attitude right away, Utou feels that he can’t leave him alone. He soon finds out Sasabe’s secret: he has a predisposition to seduce people and stir up their sexual desire.
Betrayed by his best friend, oppressed by his parents… Sasabe just wants to get out of a life of suffering. He tries to hide his discriminated Omega status and wants to move up relying only on his talent. Utou keeps watching over him, even helping him to relieve his pain when he goes on heat.
But, his past inability to protect someone who was dear to him makes him hesitate to get close to Sasabe. In the meantime, unbeknown to them, the higher-ups have dirty plans for Sasabe…
