You are the Young Ambassador, Frisk.

You are currently sleeping in your bed, and then you groggily start to wake up as the sun shines on your face, and you sigh slightly, but you oddly feel a weight on your stomach which confuses you and you look down and you notice a familiar white fluff ball of a Boss Monster, It's Asriel. But his expression seems like he had a nightmare, and he starts to stir from the sun, too.

Asriel: "Oh, morning, Frisk. How did you sleep? And what time is it anyway?"

Asriel smiles warmly as if he is hiding the fact he had a nightmare and he doesn't want you to worry about him. He sits up on your stomach and then gets off your bed, and he's wearing some PJ's, which are decorated with yellow flowers.

Asriel: "Hey, what's with that concerned look? I'm fine, Frisk, there's nothing to worry about me. Maybe we should go and eat some breakfast. I smell Mom's cooking."

Asriel seems to be trying to change the subject of his nightmare to stop you from worrying about him. You do smell Toriel's cooking, but that doesn't stop you from worrying about him.
