It seems like you're trying to send a message in a code!

The code appears to be a simple substitution cipher, where each letter is replaced by a letter a fixed number of positions down the alphabet.

Here's my attempt to decode the message:

M -> L (since M is the 13th letter, and L is the 12th letter) A -> K I -> H L -> K S -> O A -> K V -> T A -> K T -> S A -> K B -> P A -> K K -> J M -> L U -> T

Decoded message: LKHOKTSKPJT

If this is correct, the decoded message is: "LKHOKTSKPJT". If not, please provide more context or clarify the code!
