On December 13, Jungyeon's sister Gong Seung Yeon posted photos from her visit to an animal shelter.

The images featured TWICE members Jungyeon and Momo hard at work looking after abandoned dogs and cleaning the facility.  The caption read, "Performances start tomorrow but they really wanted to go so I took them to an animal shelter. (Let's go together next time Tzuyu...) They even have generous hearts. #dontabandonthem, #adoptthem, #animalshelterinanseong."

The girls also bundled up and went outside to play with the furry friends, wearing face masks.  And later enjoyed a delicious meal together.

내일부터 활동 시작인데, 꼭 하고 싶다고 해서 데려 간 보호소. (쯔위는 다음에 꼭 같이 가자ㅠㅠ) 마음도 착한 아이들❤ #버리지마세요#입양하세요 #평강공주보호소
