예정에 없었던 선물이 도착;;?

Unexpected present has been arrived ; /

티스토리 앱에서 있는지도 몰랐던 새단장 이벤트에 참여해주셔서 고맙다면서 카카오톡 이모티콘 쿠폰을 보냈네요!
...?
뭐지?
새단장 이벤트가 어떤건지 검색 함 해봐야지 ㅎㅎㅋ
It says, 'Thanks for your participating to our Tistory renewal event!' and they sent to me a coupon for use a package of emoticon in Kakaotalk(it is a well-known messenger service in Korea. How is it in your country?)
......
What is this?
I'll search about it in Naver soon! : )
