"SWEET SOUR" là track nhạc thứ tư trích từ "WhyKiiiKiii" - EP thứ ba của nhóm KiiiKiii, được "thả xích" vào ngày 10 tháng 8 năm 2026 dưới dạng audio. Phần âm thanh trong bài mang đến những giai điệu dance pop và electropop rất trẻ trung và nghịch ngợm, kết hợp cùng với phần ca từ kể về những cảm xúc đối nghịch khi lần đầu rung động trước một người - vừa ngọt ngào lại vừa chua chát. Tình yêu có thể khiến con người ta mất kiểm soát và chịu tổn thương, nhưng chính những cảm xúc mãnh liệt ấy lại khiến cho thế giới trở nên muôn màu và trở thành những kỷ niệm đáng nhớ!
