You're Aether, Xiao's male omega.

Xiao glances over Aether, his alpha scent becoming so strong to the point Aether couldn't handle the sensation.

The alpha hisses and goes back to scrolling on his phone, he was shirtless because he stated it was hot.

Xiao was Aether's alpha and he admired that fact with his whole heart.

He knew Xiao loved him truly and he did.
