The following puzzle is my next attempt of setting puzzle with variant[s] interacting with Numbered Room clues. After my previous attempt with arrows, I want to look at how Numbered Room would work with German Whisper line (which I still don't fully understand how it was named that).

Many many hours passed by and I felt like pure whisper version is too hard so I gave up on the idea... only until I realized that renban also exists. Combo whisper + renban has been quite a familiar trend to puzzle setters so at that point I didn't expect much to see the surprise that this brings up to me. The next following day, I was making an experimental puzzle with this combo and it actually worked out pretty well, I guessed, but I still felt like it's missing something satisfactory. Back to the drawing board (again), I realized another way to work out from the opening so that gave me an idea to exploit the structure and eventually after just more than an hour, I finally got another puzzle that appeared to be much more better and consistently balanced than the experimental one.

I actually want to share here earlier than usual because after this one, I'd like to revisit bunch of old puzzles that I missed on the site in these next days, man did I miss so many of them. Anyway, difficulty should lie in the range 3.5 - 4, I hope you enjoy! (Also I'll link the experimental version in the hidden comment as the bonus proof, which has a harder opening sequence)
Rules:

- Normal Sudoku rules apply for the 9x9 grid: every row, column and 3x3 box contains digits from 1 to 9 each once.

- Along a green line, adjacent digits must have difference of at least 5. Along a red line, digits cannot repeat and they must form a set of consecutive digits in any order.

- All of the cells outside the grid that interact with the lines are all numbered room clues (so they also contain a digit from 1-9). A digit in a numbered room cell has to be placed in the Nth cell in the corresponding direction of that row/column, where N is the digit placed in the first cell.
For example, if R5C1 is a 4 and R5C0 (on the left) is 7 then R5C4 must be a 7.
To clarify more, there's a 2 cells red line on top of box 1 - R01C1. It's obvious to note that outside numbered room cells don't follow the standard sudoku rules.
