I still don't get how Kyou died. At first I thought he got pushed off, but did Kagami's face just startle him so badly he fell off?
Also, since she's pregnant and there's only one chapter left, I feel like either her pregnancy will snap the MC out of it and he'll off her or maybe himself; she'll starve herself into a miscarriage, and she'll off herself from the guilt; or the ghost of Kyou will just drive Kagami psychotic enough to murder the MC. Bonus points if she kills the MC and then names the baby after him or Kyou.
