만에/오랜만에
I'm a little confused about the meaning of 오랜만에 when seeing it in sentences.
For example:
(1)오랜만에 집에서 쉬니까 너무 심심해요.
Does it means
(A)I feel boring because I've been home resting for a long time.
(B)I feel boring because it has been a long time since last time I rested at home.

My textbook tells me that ~만에 means "something happened after a period of time" so it should be (B) in accordance to that but (A) seems more logical to me, though. And here's another example:
(2)오랜만에 이곳에 왔어요
(A)I've been here for a long time
(B)It has been a long time since last time I came here.
Both (A) and (B) make sense to me but I couldn't figure out which is the correct translation of the sentence.

Would someone please tell me the right meaning and usage of 오랜만에 and~만에?

감사합니다.:)

Answer

1.  오랜만에 : after a long time

(1) 오랜만에 집에서 쉬니까 너무 심심해요.
 Answer : (B)I feel boring because it has been a long time since last time I rested at home.

(2)오랜만에 이곳에 왔어요
Answer : (B)It has been a long time since last time I came here.

2. 오랜만에 & ~만에

1) 오랜만에 
   : This is just a phrase that means 'after a long period of time'. It once meant something related to '~만에' but now it is just a phrase. So please think it as the meaning itself : 'after a long time'. Also, it is working as an adverb inside a sentence. 
              
 2) ~만에  
   - Meaning : after a certain time has passed 
   - Using inside a sentence :   ~만에 + action 
    => Meaning of ~만에 + action : after a certain time has passed, the 'action' happened 
     =>  So, ~만에 doesn't mean 'something happened a after period of time' it is more closer to the meaning of 'after a certain time has passed, a certain action happened'. I think this is where you got confused. 
     => Also, if you want to use '~만에', the same thing should not be happened during those times. 
    So for example... 
    Ex) 3년 만에 집에서 쉬었어요. (I rested at home after 3 years.)
        -> 3년 + ~만에 + 집에서 쉬었어요. (action) 
           1. This sentence specifically means : after 3 years has passed, I rest at home.  
           2. This also shows that you had never taken any rest at home during those 3 years, not even once. After 3 years you could 'finally' rest at home.

Another example... 
 Ex) 2달 만에 오빠를 만났어요. (I met my older broter after 2 months.)
        -> 2달 + ~만에 + 오빠를 만났어요. (action) 
           1. This sentence specifically means : after 2 months has passed, I met my older brother.
           2. This also shows that you had never met your brother for last 2 months, not even once. After 2 months you could 'finally' meet your older brother.

So.. ~만에 implies two things at the same time. 
 1. After a certain time has passed, the action happened.
 2. Same action did not happened for that certain amount of time.

Hope it can be a help~!

Answer

Yeah I was totally confused when I saw the first example sentence on my book, so I guess it's not my problem haha! Thank you for showing me a better phrase of 오랫동안 to replace the original one. Really learned a thing!

Answer

The first example sentence is a terrible one which is more confusing than clarifying anything.  
More logical example would 오랜만에 집에서 쉬니까 너무 좋아요, or 너무 오랫동안 쉬니까 심심해요.
(오랫동안 means doing something continuously for a long time, almost the opposite of 오랜만에)
