Out of spicy foods you made pure happiness. You give it to your sad friend こういち, who waits at the table.
こういち looks sad. But when you serve him happiness, he starts to perk up a bit. A couple more bites of happiness, and there's a smile on his face. Although when you found こういち he was depressed, down on his luck, and hiding from the government, cooking him some spicy foods seems to have brought him some happiness.
