In this sentence I don't understand the beginning "どうせ 本人と似て軽薄でキラキラしただけの---" For me it's : Anyway, they look alike, brilliant and frivolous But I'm not sure. Could someone please help me ?
And if someone could explain to me the meaning of だけの in the end of sentence, does it have the same meaning as "だけ" or does it mean something else.
だけの in the end of sentence
? Usually that's not the case, and this should be part of a longer sentence. Is this a manga? What's the context, and who does 本人 refer to?
