On April 13, one netizen created a post on an online community forum titled, "YoonA's tips on how to store leftover snacks." Here, the netizen included a video clip of YoonA demonstrating to her viewers how she stores her left over snacks to preserve the crunchiness of her chips. YoonA stated, "First you fold [the corners] vertically, and then you flip it." She then folded her snack bag downwards and then unfolded the corners, which locked the bag in place.

"For some reason, the way that YoonA talks is really charming. I find myself keep watching it because it's entertaining Lollll."
