@Oh_so_Intricate: But it's also a fact that events have already changed.
Akari might marry Hartknight, but he's not going to be king and Akari is viewed not with worship but with caution.
Hell Akari herself tried to change the game story by going for an ending that didn't exist in the first game (Aqua)
And Akari points out Tiara's an oddity since Tiara did not show up in 2nd game and Aqua's fiancee, the one that get dumped for the heroine, was someone FORCED ONTO HIM.
Not to mention since it's an otome game, there's OTHER CAPTURE TARGETS, how about redirecting Aishira to one of those?
If anything Tiara should learn from Kobayashi and Endo and try to aim for 'everyone be happy' ending.
Sure she didn't know anything about the sequel, but she can easily recognize capture targets from their looks and importance already anyway (besides those hidden route ones)
