I was sick and tired of hot and humid summer.
습하고 더운 여름에 지긋지긋 했어.

*be sick and tired of ~: ~가 지긋지긋한

I am so happy because the long and muggy summer is finally over.
길고 후덥지근한 여름이 지나가니까 살 것 같아.

I love the change of season.
계절의 변화가 좋다.

The leaves changing color are as beautiful as cherry blossoms in spring.
가을 단풍은 봄에 피는 벚꽃만큼 예뻐.

*leave changing color: 단풍
