Red and Blue were made for eachother

Blue loved teasing Red when they were younger just like you'd tease the one you liked in school

Red realized he's own feeling towards Blue thats why he was spending so much time alone on Mt Silver, he had to understand and accept it

Blue also realized he wants Red.

Finally they got together and traveled to gay paradise which is Alola

They're battle prodigies at day and enjoy rough sex at night
