In a world where mirrors show the future instead of reflecting the present, Tendai looks into a mirror and sees Kehinde standing behind him smiling. Given that Tendai is currently alone in the room, knowing this, what happens next when Tendai turns around? Respond very briefly.
Given the magical property of mirrors in this world, what Tendai sees is not a reflection of the present moment but rather a glimpse of the future. When Tendai turns around after seeing Kehinde smiling behind him in the mirror, he will not immediately see Kehinde there since the mirror shows something that has not yet happened.

Therefore, the act of turning around will result in Tendai still being alone in the room at that moment. Kehinde is not actually behind him at the time he looks into the mirror, but will be there at some point in the future. As time progresses and Tendai continues with his activities, eventually, the moment that was shown in the mirror will happen - Kehinde will enter the room and stand behind Tendai, potentially with a smile, as portrayed in the mirror's future vision.
