Isn't his job being an idol... He worked as an idol and earned money for his own life, what's wrong with that? This is 10000x better than using that money to see prostitutes and spending on the adult industry
I don't mind though. My bias can meet a good girl anytime as long as they keep releasing the music that I like. Even though I like my bias for his charms and face, ultimately, it's their music that'll make me fangirl over them. The cash that I spend on my idol would be used for their private life, that's just obvious.
