Recently, PLAN B‘s Roy shared shocking claims of being assaulted by his groupmate.

According to his posts on social media, Roy was allegedly attacked by PLAN B’s Han (Kang Wangseok), resulting in a hospital visit. Wangseok’s new agency addressed the claims in a statement, while the idol posted a handwritten apology.

However, Roy has continued sharing details of Han’s alleged behavior while promoting with the group, including the alleged sexual harassment of former member James, who departed from the group in 2024.

According to Roy, who says that he got permission to share from James, Han continually harassed James even after he asked him to stop. According to Roy’s tweet, James did not stay in the dorm.
He also included a screenshot from a video as proof, saying the full thing was too explicit to share.
Don’t you think it’s inappropriate to post this?
Sexual harassment is something that should never happen.
James was repeatedly harassed, and he had already warned that he didn’t like it, but Han still didn’t stop.
There’s actually a video clip, but it’s too explicit.
(Everyone was supposed to sleep together at the dorm, but James chose to drive home every night because of this.)— James
James also spoke about the post, confirming that he had given permission, and adding that the repeated behavior was why he did not want to work with them anymore.

เรื่องนี้เต้ยมาขออนุญาตผมก่อนลงแล้วนะครับ ตอนแรกผมชั่งใจเพราะผมว่ามันค่อนข้างน่าอาย ผมไม่เคยโอเคหรือสนับสนุนเรื่องนี้อยู่แล้ว ต่อให้มันเป็นการเล่นหรือกลั่นแกล้ง ผมก็ไม่เคยโอเคกับมัน มีการเตือนกันหลายครั้งว่าผมไม่ชอบ ผมอึดอัดกับพฤติกรรมหลายๆ… https://t.co/KFUsa0mbx5— JAMES (@Jamesnagon) April 27, 2025
Toey (Roy’s real name) asked for my permission before posting about this.
At first, I hesitated because I thought it was quite embarrassing.
I have never been okay with or supported this kind of behavior,
even if it was done as a joke or bullying.
I was never okay with it.
I had warned multiple times that I didn’t like it.
I have always felt uncomfortable with many of their behaviors,
and that is one of the reasons why I no longer want to work with them.In case someone asks why I didn’t inform the anyone or protect myself, it’s because every time I got angry and wanted to take action against the other side, they’d come in to mediate and promise not to do it again, but in the end, they’d still act the same.

There has been no response from Han or his current agency as of writing.
