yokoo and satou

the best background bois in toilet bound hanako kun. They are Kou's best friends, and are total opposites, but complete each other.
Yokoo (the one with light hazely hair and a lively personality) likes sports, and Satou (the one with dark, chocolate like hair, with a calm personality) likes baking and sweets, they are in the student committee together, and are rarely seen apart.
You could even say they are boyfriends. Husbands even. Soulmates.

Yokoo and Satou are my favorite characters in tbhk, but a lot of people don't even know who they are.
