What does ハートは赤く染まる mean? It’s from a love song about someone being completely smitten by another.
I know the literal translation is “(my) heart is stained red” but what is the meaning of this phrase?
Unless the context proves otherwise, it should mean something along the lines of:
"My heart turns red."
"My heart flushes."
To me, "stain" would sound quite strange.
