There will be no volume 3 at all, this is only two parts, not many people know this, but originally, this was a one-shot manga until it got more popular, and the audience wanted more of the story, so the author made a second part. Understand this, this manga was made in 2018, then got a second one-shot manga made in 2022. It has been 4 years, and I do believe the author does not want to continue the story because he will still be chasing his crush, since I am going to assume that the author wants to give a lesson to her readers, since some or most of us know that Nakamura-kun will never be with Hirose.
