Honestly you shouldn't.
I've already said this in previous posts, but the "after story" only exists due to the main heroines have unexplained parts of the story. In example Momoyo, her "love life" is not explained in the main story, so her after story is only about having love with Yamato.
Chris on the other hand doesn't need one, her route is a technically a "complete route" while the other heroines "isn't complete yet.
Think of it as this
Chris Main route = 100%
Momoyo main route = 70% + After Story 30%
True but when I first saw Yukie after story they only told what happend to everyone 50 years later, everyone but her and Yamato, I think that the after story for Yukie is not that great expect for the CG.
Chris in my opinion didnt need one because by the end the same thing is explained, dont know about all the other since I havent watched them yet.
