"Dear Mario"

"He's been missing for a while, I should write to him!"
Luigi has been worried for his dear older brother Mario, and the best way he can believe to check in on him (Mario requested not to follow him) is to write to his brother! All that's left to do is wait for Mario to reply!

...right?
