That's possible but by no means certain. Of the other two coronaviruses that have caused the most concern in recent years, SARS "went away" but MERS didn't.
After a couple of peaks in numbers in 2014 and 2015, the numbers of MERS cases have remained pretty steady ever since. The good things about MERS are that it never spread very widely across the globe, has a relatively low rate of transmissibility and the fatality rate has dropped as doctors have become better at treating it but it shows that coronaviruses don't necessarily just "go away" after a while, all by themselves. The coronavirus that causes the common cold is another example of a coronavirus that doesn't just go away.
Some epidemiologists have discussed the possibility that Covid-19 could become a permanent part of the medical landscape, with seasonal peaks and troughs like the flu, though presumably with a lowered mortality rate as natural immunity to it develops.
I hope that this new coronavirus will be more like SARS than MERS in this respect but the truth is, we just don't know.
