1. Summary of the incident: The shock of simultaneous hiatus

On October 15, 2025, LAPONE Entertainment suddenly announced the simultaneous suspension of JO1's Shosei Ohira (25) and ME:I's Shiori Iida (20). The agency only explained that "an incident that violated the rules had been discovered," and did not provide any details. However, the situation changed completely when Shukan Bunshun's online edition published a scoop shortly thereafter about "Shosei Ohira's two-timing relationship."

The news that these two members, at the height of their popularity, would be halting their activities due to an unexpected scandal came as a huge shock and disappointment to fans. JO1 had been performing at the Kohaku Uta Gassen for three consecutive years, and ME:I had just made their first appearance at the Kohaku in their first year since debut. The scandal, given the circumstances, shook the brand value of LAPONE as a whole.

2. The truth behind the two-timing relationship and what was reported

According to Bunshun's report, Ohira Shosei had a regular girlfriend (Ms. A). However, he was also reportedly intimate with Shizuki Iida (SHIZUKU), a junior member of ME:I who was also in the same agency. In other words, while Ohira was seriously dating Ms. A, he was also having a relationship with a female idol in the agency. If the report is accurate, his actions were not just a romantic relationship, but a two-timing that violated company rules and posed ethical issues. In particular, since there is an unspoken rule that romance within the agency is almost forbidden, LAPONE is believed to have deemed this an "issue that cannot be overlooked."

3. Relationship with his girlfriend A

Ms. A met Ohira through her work in the entertainment industry, and they began dating after he made a proactive approach. He was sincere with Ms. A and spoke words that hinted at marriage. To those around them, the two appeared to have a stable relationship, but in the spring of 2025, Ms. A discovered unexpected "evidence" in Ohira's room. This was a letter from Iida Shioriduki, which would later become the center of the scandal.

4. A forbidden relationship with Iida Shiori

Iida Shioritsuki is a member of ME:I, a sister group born from the same program as JO1, "PRODUCE 101 JAPAN THE GIRLS." She gained popularity with her clear visuals and solid singing ability, and was a highly sought-after member of the group. It is said that she and senior idol Ohira became close through joint events and interactions within the agency. However, as they both belong to the same agency, LAPONE, their relationship should have been handled with caution. It is believed that Ohira continued his relationship with A while also making frequent contact with Iida, which ultimately led to a two-timing relationship.

5. The letter that led to the discovery

The definitive revelation came in May 2025. While Ms. A was cleaning out Ohira's room, she found a handwritten letter from Iida. It was filled with words that only lovers would write, such as "I'm happy every day that we met" and "I want to be together forever." Ms. A's shock at learning that her trusted boyfriend was having an affair with a woman from the same talent agency behind the scenes was immeasurable. She consulted those around her, and the evidence was eventually passed on to a weekly magazine.

6. The full story behind the pledge and hush money

Just before the scandal came to light, Ohira sent a written pledge to A, saying he wanted to "atone for his sins." However, it has been reported that the contents of the pledge were more like a "gag order" than an apology. The pledge included provisions to keep quiet about their relationship and breakup, to permanently pay damages if any information was leaked, and even a proposal for a "financial settlement." This could easily be seen as pressure on A, and after the Bunshun report, it was met with harsh criticism from the public, with people saying it was "insincere" and "disrespectful to fans and women."

7. Official response from the LAPONE office

Following the Bunshun report, LAPONE Entertainment confirmed Ohira and Iida's relationship and the existence of the pledge, and announced that both would be suspending their activities. The statement stated that "this is a serious act that betrays the expectations of fans" and "we urge the individual involved to reflect deeply," indicating that the agency takes this matter very seriously. The agency has been hit with a series of problems since 2024, including the online casino scandal involving Tsurubo Shion, and it is urgent to prevent recurrence and strengthen internal governance.

8. Fan Reaction and Future Impact

Social media was flooded with comments such as "This is such a big shock," "I can't believe it," and "I feel betrayed." JO1's fans, known as "JAM," and ME:I's fans, known as "YOU:ME," were particularly shocked by the unusual decision to suspend their activities simultaneously. While some expressed their support, saying, "We hope they reflect on their actions and return," there was also a clear trend of people leaving the group, with Ohira-related merchandise rapidly appearing on Mercari. With his appearance at the Red and White Song Battle now in jeopardy, 2025 is likely to be a challenging year for LAPONE.

9. Comparison of the profiles of Ohira Shosei and Iida Shiorigetsu

The two were both from the same audition program series and were "successful models" nurtured by LAPONE. The simultaneous suspension of these two has shaken trust in the LAPONE brand as a whole.

10. Q&A: When will she return? Will she appear on Kohaku? Is she banned from dating?

Q1. When will the two of you return?
It is currently undecided. It has been stated that it will be for the time being, and considering the case of Tsurubo Shion, who previously withdrew from activities, it is expected to take at least four to six months.

Q2. What impact will this have on the Red and White Song Battle?
JO1 has been participating for three consecutive years, and ME:I also made their first appearance last year, but this scandal means that their participation is now considered almost hopeless.

Q3. Is dating prohibited in LAPONE?
Although there is no official statement that dating is prohibited, "behavior that damages the trust of fans" and "dating with company insiders" are prohibited. It is highly likely that this case was deemed to be in violation of these regulations.

Q4. What do your fans think?
There are many voices of sadness and anger on social media. At the same time, there are also strong voices calling for him to "reflect on his actions as a person and come back someday." In order to regain the trust of his fans, a sincere apology and action are essential.

11. Summary: The cost of losing trust and the possibility of regaining it

This incident is more than just a love scandal.

The actions of popular member Ohira Shosei have shaken the very credibility of the idol profession. Fans support idols not only because of their music, but also because they believe in their sincerity and ideals. The price of betraying those expectations is not small. However, by showing remorse and a sincere attitude, there is a chance that she will return to the stage. For Iida Shioritsuki, the hiatus from activities immediately after her debut is a major blow, but many hope that she, known for her hard work, will return with a smile. For the huge agency LAPONE, this incident will be a turning point that will require them to reexamine their brand and approach to human resource development. Whether they can regain trust will depend on their future actions.
