As Rui and Tsukasa's relationship (whether it is friendship or something more) continues as usual, Rui begins to notice something strange about Tsukasa. Determined to uncover the truth before it's too late, he tries to make sense of the symptoms Tsukasa is desperately trying to hide. What Rui doesn't know is that he is running out of time. Time never stands still, after all-and for Tsukasa, it has become the most precious thing in the world.
Basically ruikasa your lie in april au. There's major changes in the story but the main idea still stays the same.
