Dramione reunion: Hogwarts is my home.

It's been 16 years since Hermione ran away from her life in wizard world and has been living in the muggle world with her husband and kids.
Out of the blue everyone gets a letter inviting them all back for Hogwarts reunion in which they all except.

Ronald Weasley is still head over heels for Hermione and tries asking her back in which Hermione declines because she's happily married.
What will her friends all say?...What will Ron do?...
