보아(BoA)_No.1_뮤직비디오(MusicVideo)

노래 가사를 오늘 처음 들어봄.

어우 잘 썼는데..

들썩이는 리듬에 튿어질 듯 가슴 시린 가사를 담은..

Cursed thin body..

잘 쳐먹질 않으니 찌질 않는 생존근육.

허리가 길어 슬픈 미어캣 몸매 ㅠ_ㅠ..

운동을 다시 시작했지만.. 살이 찔지는 미지수 쩝..

리쌍 - 발레리노

위키드, 뉴욕 여행 (Wicked, New York)

New York at 12.24 ~12.26 + Wicked

Well, it's a pretty expensive ticket and

also New York is the very expensive city, especially for X-mass..

Nevertheless, it's literally the first vacation for me during 3 years here in Boston.

So I guess I'm deserve it :)

오아.. 정말 노래 다들 잘 부른다.
보길 잘했다.

뉴욕, 겨울 여행 (New York at winter)

Visited for just having a fun and stuck there two more extra nights due to the heavy snow storm...

정말 눈이 엄청 온 날이었다.. 일정보다 길어진 뉴욕 여행.
덕분에 후배 집에서 하루 신세 지기도 하고 ㅎㅎ

아 뭐하는 짓이지..
