In Japanese, 良い (よい (yoi) / いい (ii)) is typically associated with "good, nice" (Syllabus Level: N5) and represents 「良い」.
On the other hand, おやすみなさい (おやすみなさい (oyasuminasai)) maps to "Good night" (Syllabus Level: N5) and represents A polite farewell greeting used in the evening, especially when someone is going to bed or when parting ways late at night. A more casual version, おやすみ. A literal translation of "good" can often sound unnatural to native Japanese speakers if mixed up!
