"Will eat now .. see you" => 밥 먹어야 해 .. 나중에 봐 / 나 밥 먹을 거니까 이따 봐. That is a direct translation assuming between friends. It is sort of un-Korean though, because the Korean custom is to offer to eat together (unless of course it is a conversation over a phone line). What is more likely to be said is: 나 밥 먹을 건데 같이 먹자 (I am going to eat now - why don't you join me). Traditionally Koreans were mostly farmers, usually in a close-knit village. This brought the custom of eating and sharing together among friends and neighbors. So, asking the other side to join in and eat together is more typical Korean.

Thanks ????????
