A K-Pop star went back to work right after a trip to the ER. Fans are so pissed about it they sent a protest truck to her company.

• Fans of K-Pop idol Jang Wonyoung sent a protest truck to her label, Starship Entertainment.
• It was recently revealed that Jang returned to filming right after receiving 7 stitches for an arm injury.

"Today marks the start of the truck protest to protect Jang Wonyoung's rights," @Jangwonyoung_CN, Jang's Chinese fan club, tweeted yesterday. Attached to the tweet was a video featuring the five messages that will be displayed, along with a picture of the truck parked outside K-Pop label Starship Entertainment's office in Seoul.

"Not a single legal action, but immediately removes malicious comments about Starship? Whose interests does the management truly serve?" read one message on the protest truck.

The protest was sparked after fans found out belatedly that Jang was injured at a music video filming site, but returned to work right after a trip to the emergency room. Jang will turn 19 in August and is a member of K-Pop girl group IVE, per K-pop news outlet AllKpop.

In a radio show on Friday, the director of IVE's "I AM" music video revealed Jang had actually injured her arm during filming and was taken to the emergency room, where she got seven stitches at the emergency room.

"But even after going to the emergency room and getting stitches for two days in a row, she came back right away and pulled off all the scenes we had left," said the director Son Seung Hee on the radio show.

Fans disapprove and have displayed this through both the truck and an online protest, demanding that the company protect Jang's rights.

"The truck will stay at Starship building from 9am to 5pm daily until the agency gives out an appropriate response," the tweet read.

Protest trucks are not a new thing in the world of K-Pop. In May, fans of K-Pop boy group Enhypen sent protest trucks to the group's company building demanding a change in their song's choreography.

Starship Entertainment did not immediately respond to Insider's request for comment.
