   Summary

   "What is this feeling? Is it... a heart attack?!"
   When Rui collapses from pure exhaustion right after a Wonderlands x Showtime performance, Tsukasa is tasked with carrying his director home. He easily blames his racing heart on the heavy lifting. But when Rui starts avoiding him at school the next day, Tsukasa spirals into an overthinking frenzy—forcing him into the SEKAI to seek advice from Miku and the other Virtual Singers.

   As it turns out, everyone in the acting troupe already knows exactly what's going on. Well, everyone except Tsukasa himself.
