The day that had started on a very sweet note for Darren, it ended on a weird and complicated note. The same went for Xiu as well. While Darren got the shock of his life when he connected the dots and realized that Nora is the one in Xin Xiaosi's heart, Xiu's shocker was that mystery box that came out of nowhere.

She had thought about destroying it but right behind the riddle, it was written that the box would self-destruct if force was used. And this very point made Xiu even more certain that the answer to her every question was inside that box. That's why she was even more desperate to solve the riddle.
