Teratani the mastermind wingman yet again!
Its a breath of fresh air that Seto was able to think of scenarios like that happening after an incident such as that kiss. He actually was right on the money to how it usually goes but for Iori is different. I feel like there's two things here: One she's not showing emotion and she probably has fully accepted that Seto doesn't like her anymore and she just went with the dare. its either that or she's so good at acting that she fooled Seto that the kiss was just natural to her even though its not.
