A triptych (from the Greek tri- "three" + ptychē "fold") is a work of art (usually a panel painting) which is divided into three sections, or three carved panels which are hinged together. The central panel is the most important one, and this is flanked on either side by two lesser but related paintings. The whole is intended to be greater than the sum of the parts.

Kiss

Sanji slouches against a wall, his relaxed posture diminishing his height so that it's easy for the woman to lean into his kiss. His hands on her hips are gentle, not grabbing her and pulling her close the way he longs to. She's relaxed too, her arms looped loosely around his neck. He doesn't murmur against her lips like he wants to, and she doesn't moan the way he wishes she would, but when the kiss breaks she gives a contented sigh and leans her head against his chest. It's more than enough.

This time it's Nami who's against the wall, the bricks digging into her back as she's pushed against them by the force of Zoro's body. His hands are on either side of her, trapping her. Hers are at his shoulders, the fabric of his shirt bunched in her tightly closed fists. He's growling something into her mouth and she bites his lip. When he breaks the kiss and draws back she comes with him, clutching his shoulders for support, her breath coming in ragged gasps. He holds her tight to him, unable to think of anything else.

Zoro's sitting on the deck, his back against the ship's rail. Sanji's bent over him, yelling something about the refrigerator. The ship rocks and he falls forward into the other man, their lips connecting for a second before they spring away from each other, shouting, even though it was an accident. An accident where Sanji, who has lived most of his life on ships and doesn't even notice their movement, was pitched into a helpless Zoro, whose reflexes, almost unequalled on the Grand Line, couldn't save him.
