* mija: This is a term of endearment used for a daughter or a young woman, similar to "my dear" or "my love" in English.
Putting it all together, the phrase is a declaration of love for someone special, often a daughter or a close female companion. However, directly translating the phrase might sound a bit awkward in English.
Here are some ways to express the sentiment in English:
* My love, I love you forever, my dear.
* My darling, I love you with all my heart, forever.
* You are my forever love, my dear.
* My precious one, my love for you will last a lifetime.
The specific translation you choose should reflect the context and the relationship between the speaker and the person being addressed.
