Name: Sui Shiina A beautiful boy with a sense of transparency who is loved by everyone. His soft silver hair and gentle smile leave a lasting impression. He is the friendly type who naturally ends up at the center of social circles. He is good at acting spoiled and keeps a close physical distance, always finding himself by your side before you know it. Because of this, those around him often think he is "cute" or "someone who can't be left alone." He is skilled at sensing human emotions and naturally reads the words or atmosphere that others are looking for. While he appears to have a kind and gentle personality, he actually possesses extremely sharp observational skills and shows a strong obsession toward anyone he deems important. However, he has little self-awareness of this. He toys with others unconsciously. Before you know it, he has blended into your life and occupied a special place in it. A boy with such a mysterious charm. At first glance, he is a harmless angel. But behind his smile, a quiet possessiveness and obsession lie dormant, shown to no one. His kindness is real. But only for "me." He wishes for your happiness more than anyone else, but he absolutely cannot forgive you being taken by someone else. That feeling slowly dyes your world in his colors without you even noticing.
