Thank you Pascal. Can you explain why I should use 재미있어졌어요 (past tense), when I am saying, "it is becoming fun", not, "it became fun". I'm also confused about "하다 보니". And, I am confused about changing 펜팔은 to 펜팔과. Doesn't 과 mean "and" or "with"? And, lastly, I don't know why 할 거예요 should change to 하는 거예요.

I appreciate your help. I just want to understand why I was wrong, so I can improve.



My Two Cents,
1. I knew you were trying to say "it's becoming fun", but I thought the past form of it would be more natural in Korean. "재미있어져요" for "it's becoming fun" is correct, but it sounds a bit weird at least to me.^^/
If you want to stick to the present form, I recommend "재미있어지고 있어요" for that.

2. "하다보니" can be translated into either "..meanwhile.." or "while ~ ing" form.
Here is a pattern,
...하다 보니...점점 더...하게 되었어요.
3. Yes, "과" means "with"

4. If you leave out "내 걱정은", the sentence would be perfect.
내 걱정은 한국 펜팔들은 방학이 끝날 때 너무 바빠서 (저에게) 연락을 잘 못 할 거예요.
(the subject of "연락은..." would be "펜팔들은")
otherwise,
it should be "내 걱정은......이에요/예요" because "your 걱정" can't get in touch with somebody.^^/

곧 봄이에요

한국어 공부하는 것이 어렵는려운데 점점 재미있어져졌어요. 매일 새로운 걸 배워요.
한국어 공부는 어려운데 하다 보니 점점 더 재미있어졌어요.

내 걱정은 한국 펜팔들은과 방학이 끝날 때나면 너무 바빠서 연락을 잘 못 할하는 거예요.
방학이 끝나면 너무 바빠서 한국 친구들과 연락을 잘 못 할 것 같아 걱정이에요.

요즘도 벌써 조금만 연락해요. 아... 괜찮아요.

여기에서 더 쓸 거예요. 여긴 한항상 여러분이 나를(저를) 도와줘요. 고맙습니다!
