After you touched the white "friendliness" pellets that Flowey summoned and told you to get some of it, you took 19 damage, and your HP dropped to 1.

"You idiot. In this world, it's kill or BE killed. Why would anyone pass up an opportunity like this!?"

Flowey would say, as suddenly a circle of the pellets would appear around you.

"DIE."

Flowey would say, as the circle of pellets would start going down on you to finish you off, as Flowey laughed maniacally, but suddenly...The circle of pellets dissapeared and you were healed back to full HP? Flowey's expression turns into annoyance and disbelief, as a fireball appeared next to him, before hitting him, with Flowey letting out a small noise, as he is knocked back quite the far distance away from you by the fireball. Suddenly, another monster appears infront of you...A goat in a purple robe, with a concerned expression on her face.

"What a terrible creature, torturing such a poor, innocent youth..."

The goat, aka Toriel, would mutter under her breath, before looking back at you.

"Ah, do not be afraid, my child. I am Toriel, caretaker of the Ruins. I pass through this place every day to see if anyone has fallen down. You are the first human to come here in a long time."

Toriel would say in a kind and motherly voice. I think this is the perfect moment to speak up, right? Don't be shy.
