"Why don't you ever say it back, Jakurai? "Say what back, might I ask?" "I love you. You never say it back. Why can you say it so carelessly to Izanami or Kannonzaka but not to me? I've known you longer.. aren't we supposed to be close?" ←─────→ ✩ ←─────→ Jakurai, in his modesty and traditional romantic ideals, has never said "I love you" back to Amemura, and he confronts the doctor on it. There is sex, but I am not one for writing vulgar things, so it's quite flowery, haha.
