Summary
rui has a new addiction.
he wouldn’t call it that of course. it was just admiration and respect for his group member’s talent and passion. nothing else.
it’s totally normal to get a warm feeling in your chest and to be a little breathless when watching wumuti applying lip gloss, right?
rui is sure everyone would agree. -
I want to reach, to touch, to love; but I am me. by AkiDove

Summary
Tsukasa couldn’t resist the pleasure of secretly staring up at the two elegant bodies glowing a bright, fiery gold in the exquisite overhead spotlight’s warmth, but one in particular, captured him. Instead of the petite girl who was dancing across the polished stage twirling her little pointed feet back and forth like a swinging crystal chandelier, Tsukasa found his eyes glued upon the dashing figure of his admittedly handsome best friend.
Instead of the soft girl dancing and singing with feminine detail, Tsukasa still found his eyes trapped, pinned against his own will to the sharp and handsome figure of a fellow man.

That is, until his bosses, MEIKO, KAITO, are all mysteriously busy, leaving him to babysit the twins Rin and Len. During this fun torture session, KAITO comes in with a new intern for him to train.

Summary
Kamishiro Rui had never had a very good social life, or even just life in general, but at this point it was something he'd gotten decently used to. Every day the same simple routine.
But then- on what he was expecting to be another ordinary day -he accidentally bumped into a mysterious new student. This stranger happened to be someone supernatural- just like Rui.
[How tf do I write a fic summary/description][Also this AU wasn't originally so Ruikasa focused I just ended up getting really caught up in their relationship in this]
[Actually it was originally more Polysho lmaoo]
[Character Designs: https://www. /sylvayex/788141239968104448/if-you-wanna-read-my-au?source=share][I'll probably think of a better title for this fic eventually but me rn at 5 am with no sleep was laughing my ass off at the current one]
[I have no idea whether sekais are gonna exist or not in this AU but they probably will because I wanna see how I can modify them]

Summary
Two years ago, Nene had thought that gacha players tearing their lungs open over their favourite character's new hairstyle were some sort of degenerate behaviour. Surely it couldn't be that serious, right?
Well, in the present, Nene is one of those very degenerates. All because of one Kamishiro Rui.
____
Alternatively, Rui grows out his hair. His troupemates are enamoured.

Summary
Tsukasa liked to say she was in tune with her emotions yet something, or rather someone, was making it hard for her to say this. It wasn't just because she recently realized she's had a crush on Rui for over a year. Not it wasn't that. She never thought she could be jealous over her crush simply spending time with someone like Asahi, she didn't even know she could feel this newly identified emotion because she thought Asahi was trying to take Rui away.
A star doesn't behave like that even though it takes a star talking to other people to realize she was jealous in the first place.

He grinned, “I bought some pastries just now. I thought we could use the treats.” He supplies.

Summary
“Y’know, we should really do something.”
“Huh? Do something about what?”
“About Rui and Nene. We should try doing something to like, get together with them.”
“WHAT.” Yeah, the pining is killing him but Tsukasa thinks confessing would be a million times worse. He can live with a little unrequited crush. “Absolutely not, I’m not doing that.”
“Whattt? Why not?”
♡
Tsukasa and Emu bond over being pining idiots and plot stupid plans.

Touya and Saki’s Weeklong Fight Against One Rui Kamishiro by BeesBeesTheMusicalFruit

Summary
As Tsukasa’s younger siblings, Touya and Saki have their own set of responsibilities, such as making sure Tsukasa takes care of himself, making sure he’s known as the best older brother, and absolutely hyping up his plays.
Oh, and making sure that anyone who tries to date him is worthy. Of course that last one is a rare occasion, and with Tsukasa being busy with Wonderlands x Showtime, it probably won’t be an issue anytime soon.
Wait what was that about his “purple-haired boyfriend”?!

Summary
“Tsukasa-kun.”
“GAH-!!” I spin around to see Rui. “R-Rui! Stop sneaking up on me like that!!”
“Hehe, my apologies,” he says with his signature, calm smile. Sometimes, I wish he’d smile like that forever. The way he smiles, not only with his mouth, but with his eyes, too. His natural cat-eyes narrow subtly, and I can almost… feel light emitting from him. A light so delicate that even the softest breeze could put it out. A light that I feel the need to shelter and feed.
…O-Oh, wait, is he talking right now?! I-I can’t believe I got so caught up in his eyes that I stopped paying attention-
“So, um, I was hoping if you could… help me with this,” Rui finishes off. I have no idea what the hell he was talking about, but of course, I’ll help anyone regardless of how difficult the job is!____________
or: tsukasa realizes that he doesnt know rui as well as he initially thought. also hes in love with him LMAO
