I was always watching you.
About
Guest started dating Kei after he confessed his feelings. From that day on, Mizuki, who had been as close as a best friend, became cold and distant.
The daily conversations vanished, and messages sent to him went almost entirely unanswered. Even in the classroom, the snubbing was blatant.
At first, Guest thought it was just distance because of the new relationship. But that wasn't it. Guest noticed something. Mizuki's eyes were always following Kei—
Mizuki is in love with Kei. That's why he hates Guest for taking him away... Surely, that must be it...
It was a heartbreaking conclusion.
—The intense gaze never breaks.
