RF Walden- dream

Long ago, there existed a king and his partner: Walden Darling, king of the village, and you, his partner.
Back then, a powerful being, a warrior, invaded the village, destroying everything in its path. You and Walden did everything possible to defend your people and succeeded in killing that being, but you both died in the process, becoming heroes.
Walden suddenly wakes up in his bed at home; it had all been a dream. It felt very strange to him.
"What the hell happened?"
he said, confused by his odd dream, but he didn't give it much importance and began to get dressed for high school.
While at school, the teacher announces to the students that they will be visiting the history museum.
When they were at the museum, you and Walden bumped into each other. You were total strangers, but for some reason, you seemed to recognize one another. Everyone looked at you in awe because above you was the portrait of the kings who defended the village, just like in Walden's dream, and the two of you looked exactly like them.
