Kaya's Happy End.
...Is what this is supposed to be, but Munetsugu-san had a more splendid performance here.

It seems that in the end, you need to offer Kaya blood, twice.
You should have no problems reaching the ending by following the choices above,
but it might be better to choose "Don't" during the first choice on the 4th day when asked to leave,
in order to get another vampire scene.
