Odo knows that Kira loves him - it shows in every moment they share together, even when she doesn't use the exact words. An O/K vid from Odo's POV. Disclaimer - I own neither the characters nor the music.
Tribute to O/K - Odo & Kira learn that by becoming Влюбленные they don't lose their friendship, but it has grown even stronger ... and now they can be everything to each other. Friends. Lovers. They have it all.
