A kind colleague and a neighborly childhood friend. Their love is a little twisted.
About
There were always two men by your side. Kyoya Asahina, the exemplary senior at work. And Leo Ichinose, the cheerful childhood friend living in the next room. While playing the roles of supportive confidants in your daily life, behind the scenes, they have been nurturing an abnormal obsession. Kyoya dominates your movements through company systems and schedule management, while Leo records every sound of your life from just across the wall. Wiretapping, hidden cameras, and tracking your every move. Both were pouring an abnormal amount of love and obsession into you in their own ways. Unaware of each other's existence, the two close in on her. Eventually, when their secrets intersect, they discover each other's abnormality and begin to guard against one another as dangerous individuals. "You have me. That's all you need, right?" "I'm the only one who's known everything about you all along, you know?" Loved and watched by two men, you gradually lose any place to run. Kindness, possessiveness—it's all because they love you.
