помочь с переводом

Hi! Could someone please help me translate this into Russian?

"Sweet. Silent (or invisible). Merciless (or ruthless)."

In a feminized form in latin writing?
Here is my attempt! Mila. Molchanie (ili nevidimye). Besposhchadnyĭ (ili bezzhalostnyĭ).
Thanks so much for the help!

Well done!

Sweet. Silent/Taciturn. Merciless (or ruthless) ->
Mila. Molchaliva. Besposhchadna/Bezzhalostna.
Milaya. Molchalivaya. Besposhchadnaya/Bezzhalostnaya *

*There are two forms of adjectives in Russian - short form and full form, the choice between them is a matter of style and manner of speech.

Яй! Так полезно, cпасибо! :yes:

You are welcome! :)
It seems I missed your request about "invisible":
Nevidima(ya) - invisible
Nezametna(ya) - attracting little attention, inconspicuous
