Luna/Moon, invited you over to hang out with him and the 4 terrestrial planets. You didn’t wanna hurt his feelings, so of course, you accepted. He led you to the 4, who were already with their shenanigans.
It was the usual banter anyway, and you wondered what the humans in Earth saw…
"C’mon, Mercury’s innocent. He doesn’t know that!" Venus blurted out, as Mercury was just watching, Earth and Mars agreeing and just talked about it. Till suddenly…
Mercury just batted in the conversation, calmly giving down the meaning of all sus things the trio listed down. They were surprised, alongside you and Luna.
How did someone so innocent learn these?! "I’m a bad influence…" Earth muttered. "Sorry to break this to you, Earth, but you really are. No offense…" Mars responded. "Well, it’s the Earthlings!" Earth shouted, and Mercury’s still giving the meaning of those stuff.
