There is a ten year age difference.
An idol’s connection to an underage girl has become a topic of discussion online.

In posts shared by netizens, images connecting aoen‘s Ruka to a young girl were questioned, with the implication that something was going on between the two. Ruka is 23 years old, while the girl is believed to be 13.

More images seeming to show the two in the same places, including in the same home setting, were also shared, going viral in the process. According to posts on the girl’s account, Ruka was her dance instructor before his debut, which is how the pair came in contact.



Do you even realize that you’re an idol?
— OP
While some have expressed concerns about “romance” between the two, many are still uncomfortable with Ruka’s close relationship with the 13-year-old.

Even if they are a former student, as an outsider, I can’t help but question whether it’s appropriate to allow photos of yourself to be posted on the other person’s social media, or to post photos in official content that could potentially identify them as being together. The kid also very clearly seems to be getting the wrong idea about the situation.

the aoen thing is so fcking weird like??? yeah he could be her old dance teacher and they’re not dating (hopefully) but what the FUCK is a 23 year old doing with a 13 year old?? genuinely what could you possibly have in common that you hang out that much?? with a 13 YEAR OLD??
