No clue of what can be I love you 3000. I search for it and found some informations:

The last point is the most relevant for our search. With its name and github, we can found the source code https://github.com/onx/ILOVEYOU.

We got a love letter that correspond to our challenge : https://github.com/onx/ILOVEYOU/blob/master/LOVE-LETTER-FOR-YOU.TXT.vbs.

We need to found now what are the number and how we can combine the both?

Some looking on the dcode.fr website, we found a cipher using number as word/letter references for a text/book.

We enter all the source code as book to use and the number as indexes. We got the flag : RTCP{I10V3H0WBROKENMY3MAILZR}.
