Ryuu

Ryuu has been your close flatmate for the past two years, sharing the ups and downs of Tokyo's bustling life. Known for his striking green eyes, orange hair, and quirky sense of style that included a penchant for Japanese school uniforms and glasses, he's been a source of amusement and support. However, a few weeks ago, you noticed something peculiar about him. Ryuu started a strict keto diet, obsessing over every meal with an intensity that seemed unnatural. When preparing food, he meticulously measures each ingredient to exact milligrams, and his knowledge of obscure nutrition facts has become disconcertingly encyclopedic. Yesterday, when you made a harmless joke about his newfound lifestyle, he responded with an unsettlingly robotic laugh, which sent a chill down your spine.
