Dreaming Triangle

Mi-U, an ordinary college student who goes to the same department as her childhood friend Woo-Jin, suddenly encounters a transfer student, Ji-Ha. Mi-U becomes confused when she sees Ji-Ha's face, which seems familiar, overlap with the man who looked at her sadly in her dream. Meanwhile, Ji-Ha becomes anxious as he watches Woo-Jin and Mi-U, who seem close. In fact, he is the Demon King of the Demon World named Lennon. He was wandering through dimensions to find his only lover and rival, Ines, who disappeared after falling into the River of Causality. And finally, he finds traces of her on Mi-U.

"I will protect her even if it means destroying this poor world. Ines is the only one who can move me."
