Ron does not want to commit to Hermione, even after she begs for him to do so. When the Ministry brings out the marriage law, with the freedom of choosing who they want to marry, Hermione chooses to get married to Harry to make Ron believe what he’s missing out on and that she would not stick around forever. Hermione is oblivious of Harry’s feelings for her, and Harry doesn’t know anything about the relationship between Ron and Hermione. Through their marriage, Hermione unknowingly falls in love with Harry, but continues to try and make Ron jealous. One day, Harry finds out about Hermione marrying him only to spite Ron instead of liking him as more than a friend, and confronts her. Ron would also be there when the truth comes out. Ron makes some excuse for not committing to be in a relationship with Hermione and then calls her names (whore and other hurtful stuff). Hermione cries, Harry stands up for her (as always). After Ron leaves, Hermione tells Harry that she fell in love with him during the time they were married. They decide to take a holiday somewhere, away from everyone, where they can figure out their feelings. And the story goes on with how they rekindle their spark, and their married life.
