Answer:
Medieval romance is a genre that tells about the adventures and values of medieval aristocracy. Characters are knights, ladies, kings, queens, and other members of the aristocracy. The plot of medieval romances often contains conflicts between feudal allegiances, quests, the endurance of ordeals, and the progress or failure of love relationships. Supernatural creatures and phenomena are also a common occurrence.
Sir Gawain and the Green Knight is a famous example of medieval, chivalric romance. Sir Gawain is a knight, making him the typical hero of this genre. He is on the quest to find the Green Knight a year after their first encounter. In the end, it turns out that the Green Knight was just a lord of one castle transformed Morgan le Fay's magic. All of these elements make Sir Gawain and the Green Knight fit into the genre of medieval romances.
