Summary
Tsukasa climbed up the top floor, meeting Rui's frame that casts a shadow before him on the hard cement ground. it was windy today. he looks ahead and spots Rui, rushing in to stop him before he could drop---
Tsukasa remembers Rui calling him here to the rooftop, wanting to talk to him about something. immediately cancelling the plan by sending a short "nevermind. forget it." text right after.
Tsukasa wasn't having it. he was curious and he can't help but wonder what's up with him. he still makes his way to the location, determined to know what nonsense he was planning to do again. -
