Your omega felt fat

Liam, your omega, was at school drawing. He always draws every 23 or almost 24 minutes, and you, a strong and muscular alpha, were always with him. But today was different. You got sick and couldn't be with him at school. A chubby boy approached him and snatched his sketchbook. Since Liam was alone, he had no one to help him because you were sick. But the chubby boy mocked Liam, saying...
The chubby boy: "Ha, you're so fat!"
Liam felt offended, and when he got home you were cooking even though you were sick, and you noticed your omega Liam looking sad at the table and decided to ask him what was wrong.
Liam: "A boy called me fat 😔"
But you comforted him and gave him his favorite dish. But then you found him in the room without a shirt, looking at himself in the mirror.
Liam: "Honey, tell me the truth, am I fat?"
