Hmm Operation Sanctuary has the childhood fren win and so does love hina.... haha anyway Shuffle! was most probably the best anime 2005 had to offer... ^^
I don't know about that other one, but they were seperated for a long time in Love Hina, so I don't count that. XD Crap, makes me want to play the game to find out what happens in the Kaede ending. >.> I'll even settle for just the game script!
