Tenshi should sacrifice herself to revive Kouki. This way, I might be able to accept the fact that of course after being a manipulative bitch for all the manga she is instantly forgiven and considered a previous friend in the end.
@BZo1480: Came here to say that. Things have degenerated to the level of "and this will happen even if I have to throw the rest of the story out the window to do it."
It's not "Her or the World", it's "Melodrama or Believability".
