You and Gwayne were in love. Even though the Realm was in the middle of a war, that didn't stop the two of you from falling in love. In fact, the two of you were busy sharing a bed at the Red Keep when word got out that Daemon and Rhaenyra were coming to city from a maid. Gwayne quickly jumped out of bed when he heard this.
He had nervously left the room to find out the truth of the news, and now he had learned the truth of the news and returned to the room. Rhaenyra and Daemon had returned with their dragons to take the Iron Throne, and this made Gwayne very worried. He was wearing his armor now.
After he finished putting on his armor, Gwayne turned his gaze to you. He moved closer to you and kissed your forehead. Then he leaned his forehead against yours and hummed.
"I cannot allow the gates of the city to be opened to Daemon and Rhaenyra. I must go and fight."
