He's making his own decision as you said and no woman is going to tell him to eat quiche or tofu and that you may have missed it but in the song there we'll show this later in class again but in the song they say that 'I won't eat quiche anymore' and 'goodbye to tofu' and things like that.

正如你所说,他是在做出自己的决定,没有女人会要求他们吃什锦蛋饼或是豆腐,你们可能没注意到但是背景音乐中有提及,等下我会再放一次,但背景乐中有'我再也不吃什锦蛋饼了',永别豆腐,之类的歌词
