What she expected was a normal fan interaction, but it turned into a nightmare when fans started attacking her appearance and routine with insensitive comments. What did she do? Red Velvet Seulgi jokingly added she treats herself with beer after her running routine, but this particular joke, or some may consider detail, prompted shocking criticism from the fans on her weight gain.

One of the fans commented that she had gained a lot of weight lately. However, Red Velvet Seulgi admitted she had put on some weight and wanted to cut a couple of kilograms in the coming months.

She later explained that the change happened due to a messed-up schedule after a recent trip. According to Seulgi, her sleep schedule is irregular, her digestion was off, and my overall shift in the routine made it all the more difficult to place things in the right order.

Why Fans Mock K-pop Idols for Weight Gain?

As we saw many cases where K-pop fans mock their favorite K-pop idol for their weight gain in a brutal way and mistreat them online and offline at the concert by clicking pictures and uploading them online with uninvited fan commentary. However, many fans report that they do this out of concern and not really against the K-pop idol. Their weight gain is not good for their health, and mocking them in such instances makes sense to us.

Whatever the case, industry standards do not allow fans to comment like this on K-pop idols’ posts on the internet. Making such indecent remarks and body shaming is not part of ethical behaviour at all. Therefore, many fans step up in defense of the idols whenever these issues arise. We urge people not to make such observations and share online, as it directly impacts K-pop idols’ mental health and, in some cases, physical health as well.
