Maybe he is ashamed of it. Some past works might not be up to his current standards, or perhaps there are elements in the novel that he doesn't want to be associated with anymore.
The player might change the title and his name associated with the novel so that it becomes difficult to trace back to him. He could also use some legal means like copyright restrictions to limit its availability if possible.
I don't know for sure as I haven't read it. But most likely there is the player himself who is the central character. There might also be friends or foes he interacts with who play important roles in either trying to uncover his past or helping him keep it hidden.
Since I don't have in - depth knowledge of this light novel, it could be that the 'player' has a dark or complicated past. Maybe he was involved in some sort of scandal or had a difficult upbringing. The story might show how his past affects his current actions and relationships within the context of the light novel's world, whether it's a virtual game world or some other fictional setting.
Maybe he has some dark secrets in his past that he doesn't want to be known. For example, he might have been involved in something illegal or unethical that could damage his reputation in the world of the web novel.
It can create suspense. Readers will be curious about what he is hiding and keep reading to find out. For example, it might be revealed gradually through flashbacks or other characters' investigations, which adds an element of mystery to the story.
His Gryffindor friends could be his teammates. Ron could be a goalkeeper, using his large size to block the goal. Hermione could be the team's strategist, coming up with clever plays. Neville could be a strong defender, using his new - found confidence from Hogwarts days.
I recommend "Food Emperor" to you. The male protagonist, Wang Yan, has a noble status. He is an alchemist in the Food Continent. Moreover, he did not hide his identity.

There were three main reasons why the Qing Emperor hid his strength. First, he dodged the M82A1 Barrett sniper rifle. The Qing Emperor had once been killed by Ye Qingmei with a Barrett sniper rifle. This caused him great shock and fear. In order to track down the whereabouts of this long-range weapon, the Qing Emperor did not dare to expose his Great Grandmaster strength. He hid in the palace for twenty years and secretly created a heart protection mirror that could block Barrett sniper rifles. Secondly, the Qing Emperor was worried that his plan to murder Ye Qingmei would be exposed. Finally, the Qing Emperor hid his strength to spy on his opponent's strength so that he could better plan a unified plan.
