What to do? LxReader [Discontinued]

A few weeks have passed since L died and you took his place. Everything has been going smoothly, Kira is as good as done and the case is almost closed. You decided to quit being 'L' after this case has ended and soon after quit detective work altogether. It was too difficult for you to continue. But you can't leave this case. Kira had to pay, Light had to pay. Days passed and slowly turned into weeks. You soon forgot to sleep and you didn't notice when day turned into night. 
Soon after  the Kira case closed and you were left alone in HQ. You decided to make an official announcement about L's death. Though nobody would care anyway. You often received letters from Matsuda and Misa (who was diagnosed with some form of Post-Traumatic Stress Disorder). 
But one day you received a letter that seemed out of place; 

My dear Eve E. Takashi,

With happiness in our voice we tell you the good news; 
After consideration you have been chosen for the roll of  Mei in the new season of 'Meet me there', 
airing this summer. You were chosen because of your outstanding acting skill during the audition 

See you soon,
Lawliet A. Wakada

Eve E. Takashi was an alias of yours but you hardly ever used it and this Eve was a 16-year old high school student. Why would someone use that name to audition? And how would they knew you lived here?
You took another look at the letter and noticed something; The some sentences seemed out of place and the letter didn't make any sense. You went to the kitchen and grabbed some cake, you sat down and thought about the letter.
First. There is no one that would call Eve 'My dear'.
Second. The second season of 'Meet me there' had been airing since this summer, they were way to late for her to play any character.
Third. Most people would say 'I hope to see you soon' Instead of 'See you soon'.
Fourth. Why bother saying she was chosen because of her 'acting skills'.
Fifth. Why is this person saying 'We' instead of 'I' seeing as he used one name to sign the letter.

This letter just didn't make any sense at all. Until you noticed something. There was a secret message within the letter. And this message did make sense.
