  That's all. Cheer up!

Last sunday I went to 찜질방 with mon, younger brother, grandfa, and grandmon

We had great time. I want to go therer again.

찜질방은미국에 없으니 그냥 찜질방이라 하겠습니다.

i went to the 찜질방 with grandma, grandfa, mommy, little brother and me.

i had a great great time.

i hope to go to there again (with my familly).

그냥 제가 평소 쓰는 어휘들로 한거니 더 좋은 리플 있슴 사용하시길..^^
