카카오톡 테마 - Good Night Sweety is a new personalization app for Android developed by COGUL. This free app lets you customize your KakaoTalk messenger with a charming and sweet theme that features a lovely girl in a shiny night.

The app is easy to use and apply. After installation, simply run the app and click on the "Apply" button to automatically apply the theme to your KakaoTalk messenger. However, it is important to note that the keyboard does not apply with this theme. For more themes, you can visit Cogul app or check out the work of artist Seolgi at their photographer gallery or blog.
