Ron Weasley and Hermione Granger do fall in love, this is confirmed in the epilogue of Harry Potter and the Deathly Hallows, where Ron and Hermione are married and meet Harry and Ginny (who are also married). Ron and Hermione are saying goodbye to their children, Rose and Hugo Weasley. Ron and Hermione have liked each other for a long time. For example, Hermione was upset and jealous when Lavender Brown (played by Jessie Cave) and Ron where seeing each other in Harry Potter and the Half-Blood Prince. This also happened in Harry Potter and the Goblet of Fire, where Hermione and Viktor Krum are seeing each other and go to the Yule Ball together. Ron was jealous this time.
