A bad apple
"Tokio boy band member apologises for kissing schoolgirl"
It was so stupid of him to have conducted such an unthoughtful doing and ruined his entire career as a musician.
He has disappointed so many fans not only in Japan but in overseas.
He may likely be expelled from the group or may quit voluntarily.
Nowadays, Japanese society is getting more and more relentless in condemning this kind of wrongdoing by individual, especially by celebrities.
I feel this tendency is somewhat unhealthy and even a little dangerous for our society .
I cannot say how, but I am quite sure majority of Japanese would agree with me.
