See you soon. = 이따봐.

1. 너무 is only for negative sentences. Often translated as “so” but is more like “too” or “overly”. Koreans also use it in positive sentences like “너무 예쁘다" or “너무 좋다" all the time but this is technically incorrect so for more proper sentences use 정말 instead.

2. Better to say 나중에 instead of 미래에 (미래에 lit. in “the future”)
