Summary
Tsukasa is unhappy with his actor life as he always wanted to be an idol, to dance, sing, and make people smile. Rui is content with his life, but he has always been haunted by the fact that he was the one who caused WxS to split apart. He and Nene still talk, same with Emu, but for some reason he lost contact with Tsukasa after highschool, maybe it's because Tsukasa hates him for what he did, but maybe he'll have another chance to speak with him and get the full story as fate seems to have brought them back together.

Summary
"let's get started, Shira'." the blonde starts, holding out his fist for a quick game of rock-paper-scissors. the store-owner sighs, giving in to the older male.
immediately after losing, the shorter male grabs the bottle, taking the shot glass and filling it up. he soon brings it to the younger male's view, the office worker gulping it in one go. "see? not so hard, right?"
the sharp liquid trails down his throat, making him grimace on his seat, but hiding it under his hand on his face. he looks at the younger male, playing another game of rock-paper-scissors, now beating him. he watches as the man prepares a drink for himself, the well-composed librarian was having second thoughts about this; but still finishing the glass.
"now, let's start the real game!" the blonde exclaims, smiling smugly while doing so; too confident to think about the consequences, unaware of the mess he'll be later on.

Summary
Ruled by the Gods, the earth was divided into pieces. The dark kingdom, ruled by Rin, the light kingdom ruled by Len, the sea ruled by KAITO, the eternal forest ruled by MEIKO and the love ruled by Luka. Miku was the one all of the above, keeping then in peace. But one day, the war between the light and the dark broke everything. All the Gods suddenly vanished.
The two kingdoms light and dark, never got along. Despite being from the dark kingdom, Rui lives in between the kingdoms that belong to no one. He was an independent wizard, per say. While Tsukasa lived in the light kingdom.
Rui will betray his own kingdom to help Tsukasa in the final battle but little did everyone know, because of the Gods, the disaster stroke...

Summary
Rui could roll his marble and beat Tsukasa and get out of here with his life. But something… held him back.
Maybe it was the way Tsukasa had just said his name.
Maybe it was the tears in those beautiful sunset orange eyes.
Or maybe it was just the fact that it was Tsukasa, the most beautiful and charming boy he’d ever known. And perhaps it was because he could feel the fear radiating off of him, and that he could see the way his chest rose and fell irregularly, clearly choking up.
Rui rubbed the marble between his fingers.
It slipped.
It hit the ground.

Ruikasa as JiByeok playing marbles! What could go wrong?

Summary
“It’s only natural for a star of my caliber to capture attention!” Tsukasa declared, his voice rising with theatrical pride. “To be recognized as worthy of continuing my performance is the highest praise one can receive!” He swept forward in a grandiose bow, golden hair falling across his face. “Thank you, Rui, for being such a loyal viewer of the Tsukasa Tenma spectacular!”
Rui’s eyes lit up with genuine delight. This was exactly why Tsukasa was special—he responded to Rui’s darkest thoughts not with fear or judgment, but with his own unique brand of brilliant madness.
“The pleasure is all mine.”
