Души не чаял (dushi ne chayal) is a beautiful Russian idiom that literally translates to something like "to not expect a soul in someone". It is a poetic phrase that doesn't make much sense when translated word-for-word, making it a fascinating expression to learn.
Its actual meaning is to dote on someone, to be completely infatuated, or to love someone to distraction. In the song, Jony sings "В тебе души не чаял" (I doted on you) to express the sheer depth of his past feelings, which makes his current heartbreak feel even more profound.
This song sets a very specific mood right from the start: "Вечер / Питер / Ветер" (Evening / St. Petersburg / Wind). It's a classic breakup song, but with a twist. The singer is heartbroken, saying things like "Без тебя я жить не смогу" (I can't live without you). He feels the loss physically, wondering, "Как же я усну без твоих губ?" (How will I fall asleep without your lips?). It feels like a very dramatic, end-of-the-world kind of sadness.
But then, we find out why it ended. It seems there was some dishonesty involved. He sings that her tears seemed real, but then adds a sharp little correction: "Но не все" (But not all of them). He saw something in her eyes he didn't want to see. Now, he's leaving, and even though there's a "ком" (lump) in his heart where her "фантом" (phantom) lives, he's letting the wind blow his sadness away. The wind becomes his silent friend, the one thing that helps without needing to know the details.
