hi~~ what can i do for you?

Well it's very hard to explain. In case of your example sentence, it include some meaning of "because'. ex) I can't live without you, you are my heaven ; 난 너 없이 살수 없어. 넌 나의 천국이야. --> I can't live without you because you are my heaven. : 난 너없이 살 수 없어. 넌 나의 천국인걸... But normally it is shorten form for "~~ 것을" ex ) 새차 사는 걸(것을) 고려해 볼까? (Should we consider buying a new car?)

'구요,' is a kind of conjunction liaising between former sentence and rear sentence. Meaning of '구요' is "~~. and ~~" (not exactly but similar) "~구요,"'s standard form is "~고요," and 고요, = 고(and} +요,(honorific). EX) 시장에서 모자하고 구두를 샀어요. 그리고 점심도 먹었어요.= 시장에서 모자와 구두를 사구요, 밥도 먹었어요. (I bought cap and shoes and also had lunch in the market.) But if they say '시장에서 모자와 구두를 샀어요. 점심도 먹었구요", it's meaning is similar with above but it include "waiting hearer's opinion or respond" a little. If you read as following example sentence, probably you can understand more easily. Daughter ; I bought a cap and shoes in the market. Mom :........... Daughter ; Also had lunch....(^_^;) Mom : So.. how much did you spend in all? (-_-)++ 딸 : 시장에서 모자랑 구두를 샀어요. 엄마 :.......... 딸 : 점심도 먹었구요.....(^_^;) 엄마 ; 그래서 다해서 얼마나 썼어? (-_-)++

I misunderstood what you mean so i deleted my answer. "pascal"'s answer is correct.

I got it...then I would like to recommend "세란" (SERAN) "세" is meaning of "world" and "란"is meaning of "orchid" So "세란" means 'most beautiful orchid in the world" And further more, when your friend call you, pronunciatio would be "SERAN-A" including your real name. and it's pronunciation is pretty and classy in Korea.

I think that name of singer familiar to me. Is that K-pop?

pretty = 이쁘다, 예쁘다 (same meaning) Beautiful = 아름답다. 1. you are so beautiful = 당신 참 아름다워요 2. you are so pretty = 당신 참 예뻐요 (이뻐요 also ok) It's almost same. When you like picture, you will say "와... 이 그림 정말 예쁘다' (wow this picture is really pretty) or "와.. 이 그림 정말 아름답다' (wow this picture is really beautiful) Both will be OK. But in case of baby, it would be a little strange if you say "와~~ 이 아기 정말 아름답다" (Wow This baby is really beautiful), I guess english is also same. In case of above, "와~ 이 아기 정말 이쁘다" (wow this baby is really pretty) will be more natural. Because "이쁘다" " 예쁘다" (pretty) has some meaning of "cute" i think. '아름답다" (Beautiful) has...well...sort of mature feeling? just my opinion. ^__^

A : 어떻게 지내세요? (How are you?) B : 잘 지내요, 당신은요? (I am fine, how about you?) A ; 괜찮아요? (Are you OK?) B : 전 괜찮아요. 당신은요? (I am fine or I am OK , how about you?) It would be changed according to asking form.
