Summary
A flood of anonymous love letters is turning Isagi's quiet high school life upside down. The sender remains a ghost, leaving behind no identity except for a bizarre signature: Monster. At first, Isagi is unnerved by how intimately this person knows his habits. But under the heavy, nostalgic heat of the Japanese summer, the distance between Isagi and his mystery writer begins to shrink. The clues point to someone closer than he ever imagined. If Isagi can just piece the puzzle together, he might find that the "Monster" in the letters is the very same boy walking beside him.
Who would've thought that maybe he did indirectly knew his secret admirer. Maybe this secret admirer was closer than one might think..
He just has to connect the puzzle and find out who.
