    Summary

    Tsukasa had convinced himself his goal was to make people smile. To be the best star in theater there was. To his personal standards, he’d failed in both. It wasn’t difficult to determine. He’d especially noticed it recently. During performances, he’d noticed small mistakes he’d made during singing, choreography, or while delivering lines. Nothing was ever perfect, like he needed it to be. His friends, on the other hand, were always able to perfectly project their voices and sing the melodies instructed of them without fail. Was he really making the show any better?

    If he were to withdraw from the troupe, would they really notice any difference?

    Tsukasa Tenma is the shining star of the WonderlandsxShowtime theater troupe. This, of course, requires perfection and constant practicing. However, this unhealthy mental state Tsukasa develops results in extreme stress and the accidental destruction of his SEKAI.

    ( tags will be updated as the story goes on !!! this does cover some kind of heavy subject matter though so just as a fair warning )
