Summary
𔓘 Tenma Tsukasa, Kamishiro Rui, and Kusanagi Nene are the sort of children who, when the grown-ups are fast asleep, slip away into the night to their secret treehouse, hidden high among the trees. There, by lantern light and starlight, they play pirates and read tales of their most beloved heroine—The Whimsical Phoenix. They say she flies through the skies each night in search of jolly little friends to whisk away to Neverland—a wondrous place where dreams never wither, and no child need ever grow up. But what are three ordinary children to do… when they find that the Whimsical Phoenix is real?!

Summary
“I think I- like Emu.’ Tsukasa stammered, subconsciously biting his lip.
Rui didn’t answer, not immediately, he blinked slowly and set down his tray on the table, making barely a sound. He tried his best to smile, but it felt stiff, as if his eyes weren't a part of it. Looking up, he tried to force a reaction. He really didn’t wanna be a part of this.
Tsukasa raised an eyebrow, Rui’s silence felt a little too…weird, it wasn’t anything like him…at all.
“Ah,” He finally said something, “Is that so?..” his voice, quiet and careful, as if something was swallowing him whole, he couldn’t say why, but it's a little too soft.
He didn’t know why he was upset upon hearing that sentence. He didn’t even like Tsukasa, he never did like Tsukasa. so.. why is he so disappointed? Why does his chest feel so tight..?
OR:
Rui likes Tsukasa,
Tsukasa likes Emu, Oh no. -
