The way you describe finding love as opening a “low door in a wall” that opens to “an enclosed and enchanted garden” makes my heart happy.

But I was in search of love in those days, and I went full of curiousity and the faint, unrecognized apprehension that here, at last, I should find that low door in the wall, which others, I knew, had found before me, which opened on an enclosed and enchanted garden, which was somewhere, not overlooked by any window, in the heart of that grey city.

Evelyn Waugh, Brideshead Revisted.

(I watched Downton Abbey last week, which reminded me of the Granada Brideshead series from the 80s.)
