Summary
When Tsukasa receives a message insisting he stop by Rui’s house one morning to test a new invention for one of their shows, he agrees without a moment’s hesitation. While he leaves much taller, it comes at an unbearably high expense: he has to go the day pretending to be his most beloved, most villainous director.

Summary
I don't know how to summarize it, but it's a really silly fic focused on Rui's relationship with the rooftop (and by extension other people) and how Tsukasa's presence in his life has altered that. Features some probably not that well written action scenes. It's 1 AM. I'll update this if I think of something better.
Writing this late at night did not do me any favors. I cannot keep track of days for the life of me. Oops.

pretty much abandoned at this point sorry

Summary
The term star-crossed lovers is derived from the belief that stars dictate the fates of humans. As such, when Rui looks to the sky, he can only see the love he is denied, not the wonderous constellations Tsukasa speaks of. One day, he'll surely understand the beauty of the night sky, won't he?
