The two brothers decide to go for a moon-watching expedition, but the weather is fine, so they decide to wait in the east room of the palace's scriptures library. The brothers decide that they should wait there until the moon goes up, but they decide not to tell anyone about their intimate relationship until after the moon has gone up. They decide that the scriptures library is a place where no one can find them, and they wait there for a few hours. The next day, the sisters ask the brothers for a date after twilight, and the brothers agree to go to the east part of the library to look for them. When they arrive, they find a huge fire in the library, which the brothers are unable to put out because of the size of the fire.
