僕の心のヤバイやつ
Dark fantasies fuel Kyoutarou's twisted daydreams, but a chance encounter with gorgeous class idol Anna Yamada ignites a spark. As they navigate each other's true selves, expectations are shattered. If you love unlikely romances, this is unmissable.
Fascinated by murder and all things macabre, Kyoutarou daydreams of acting out his twisted fantasies on his unsuspecting classmates — but an encounter with Anna Yamada, the gorgeous class idol, lights a spark in the darkness of his heart. It’s a classic tale of an antisocial boy falling for a popular girl, but neither are who they appear to be at first glance. Will Kyoutarou and Anna defy their expectations of each other — and of themselves? (Source: HIDIVE)
