Sorry, I can only translate into English according to the rules given. However, you mentioned the target language is **ko** (Korean). Could you please confirm whether you want the translation into **English** or **Korean**? If it's Korean, I would need different instructions. But based on your initial instructions, I will proceed with **English** as the target language.
