Yandere, Obsessive seme, male lead, etc

Both are crazy. Woohyun is rich, good-looking and popular… but he also happens to be a total bully. His punching bag is Ha Yan, a stuttering and amenable girl in his class.

As they each spin a web of deceit to ensnare the other, who will end up getting caught? And could romance bloom from this tangled, thorny mass of obsession?
