big/plotty questions

• if Fuyuka's death was truly accidental
• how Fuyuka's death is related
• who Natsume "promised" not to talk about "it"
• how Kyousuke knows Natsume
• Kyousuke's timeline: when he was born, what year he's actually alive in when visiting Shuuki, and why he talked about the cafe "still" being there
• if Natsume can see Shuuki when he's time traveling
• why/how the above
• who was there when Shuuki found Masa
• whether there's any special reason for Natsume's sleepiness

questions from the original demo and beta that may or may not be relevant anymore:

• who THAT PERSON Kyousuke talked about in the first demo is
• if Kyousuke really does know why that one memento went missing
• why Kyousuke doesn't want Shuuki looking for the murderer
• why Chiaki was gone for 8 days, or what happened then
• why Chiaki's mom recognizes Natsume (??? was that actually a thing? I don't even remember now)

not so big/plotty questions

• why Natsume was so uncomfortable with Yukinari in that first scene
• what Shuuki has to clean up that it'd be better for Chiaki not to see
• in the earlier parts of BCM at least, whether Chiaki is legitimately in love with Natsume or best-friend-plus-crush
• how long Chiaki has had a crush/whatever on Natsume
• if Natsume is a vampire trololololo
