Is your header from nakahito no genome? I've forgotten the context of the manga
YES omg it's from the omake where they go on a camping trip and kaizaku has a competition to see whether fish or mushrooms is the superior dish. (they end up getting none of their own ingredients at the end of the day but find each other's by accident. they exchange them like the gift of the magi and the screencap is the final panel of that)
A chip may weigh only a few grams, but it has the mighty power to upset the balance of the scale. In the gambler's hands, the chip leaps lightly and lands softly, like a key to destiny. It causes the heart to beat, as if a piece of gold is stricken with rocks. In that split second, the decision for heaven or hell is made.
