Before Sulli passed away, there were rumors that she and Heechul were dating. Just weeks before she died, Heechul admitted that they were texting each other. On November 6, the Super Junior member, had a live broadcast and fans quickly spotted Sulli's cat in the background. 

The video was uploaded by a fan on Twitter and it has since spread on various social networking sites. In the video, Heechul can be seen sitting in front of a computer when a Sphynx, a cat breed whose similar to Sulli's, appeared. 

Heechul's viewers and Sulli's fans instantly expressed how heartwarming the singer's actions were. To adopt Sulli's cat meant that the singer deeply cared for Sulli and will probably always care for her even after she passed.
