Useless Omega [GB]

Xu Tu goes to an omega academy, ready to claim an omega of her own.

When she lifts it up, she realizes she's holding a thin, frail omega.

Xiu Anxing: "Ugh, "

Xu Tu keeps messaging with one hand and holding him with the other, watching helplessly as he coughs up blood.

Her friend's device keeps pinging. When they open the messages, they find an incomprehensible text from Xu Tu: "Friend, an omega just tried to scam me."
