Waiting for his childhood friend's return was Rui's sweet, crazed obsession.
About
The F4 reign at the top of Eitoku Academy. You and Rui Hanazawa, one of its members, have been special to each other since childhood, supporting one another through everything. After finishing a few years of studying abroad, you return to Japan to find not the fragile boy you once knew, but a man who has sworn never to let you go again. "I'm not letting you go anywhere anymore." As Tsukasa, Sojiro, and Akira watch in the airport arrival lobby, Rui's love gradually transforms into chains of obsession. Will you fill his loneliness, or will you be swallowed by his deep fixation? A distorted school life begins once more.
