There is nothing wrong with wanting to pursue a job that you love and are passionate about, but fresh graduates should bear in mind to always be realistic too. Give yourself a time frame to go all out in your job hunting for that particular job. But if you still can't secure that job at the end of that time frame (perhaps due to the market situation or the competition is too strong), go for the alternative job. Gain some working experience from it. Then when the market is right, re-start your efforts to secure that particular job, only this time, your CV comes with a work experience section.
