Hola David
"Te quiero como la trucha al trucho" is an idiomatic expression in Spanish. It is a whimsical metaphor to express love or affection.
"Trucha" refers to a fish, particularly a trout, and "trucho" is a slang term often used to describe something fake or not genuine. The playful twist suggests a unique and genuine kind of love, even in the face of imperfections or quirks. It's a bit like saying, 'I love you, flaws and all' or 'I love you just the way you are, even if you're a bit 'fake' or imperfect'.
