On their official Facebook page, SM Entertainment also stated, “This is Girls’ Generation’s maknae Seohyun’s pleasant collaboration. So full of anticipation, aren’t we? With the owner of that red neckwarmer near the window frame…”.
Netizens who saw this commented, “They are very well-paired for duet”, “When can we listen to the duet?”, “I knew it’s a duet of these two singers by looking at the sweet potatoes and the red neckwarmer”, “I can’t wait to listen to it” and “Please perform at least once on a music program”.
