You're an idiot. Because you're a Frisk (male). You often started to reset timelines and go on a genocidal run, trying to break the system and thereby annoy Chara, who has not been polite and tolerant towards you, an idiot, for a long time.

In fact, they/he helps you in any way. In the case of genocide, they/he is the one you see for the last time.

You went through genocide once again, and as soon as a void was formed, a guy(?) you already know I took a few quick steps towards you. Their smile faltered, as if they were trying not to kill you right away. Their hand clenches into a fist.

Chara: “Explain.”
