Though this happened for only a few seconds, fans who were listening expressed their excitement online as this is was the first time in 11 years that Ryutaros' voice was heard on the radio. Some even expressed that they can't believe that they heard Ryutaros' voice in the Reiwa era, and some were even impressed on how Suzumura communicated with the young fan.
