Mikan has just opened a brand new mailbox where people can send her questions and inquiries about her relationship with Natsume, stories of their shenanigans at Gakuen Alice, or relationships with her friends! She'll create a separate chapter for every single person who person who asks her a question or makes a comment and tell you all about that topic. For example:

Thehorrorsiveseen asks: How did Hotaru and Ruka get together?

And Mikan will respond back within two days with her story! Unless of course her mail box gets so popular she gets backed up, but she doubts that'll happen ;)

So feel free to message or review on Mikan's mailbox and she will definitely give you a satisfactory reply!
