Since I haven't read this light novel specifically, it's hard to give a detailed account. However, based on the words, it seems that the story might revolve around a male protagonist (shounen yuusha).

Since we don't really know the details of 'shounen yuusha wa isekai wo gyuujiru novel', it's a bit of a stretch to recommend similar ones precisely. However, in the isekai genre, 'Re:Zero − Starting Life in Another World' is well - known. It has a young male protagonist who has to face many difficulties in an isekai world. Also, 'Konosuba: God's Blessing on This Wonderful World!' has comical elements along with the isekai setting which could potentially be somewhat similar depending on what 'shounen yuusha wa isekai wo gyuujiru novel' is really about.
One could be 'Overlord'. It also has a male protagonist in an isekai setting with a lot of power - much like what the title 'shounen yuusha wa isekai wo gyuujiru' might imply. Another could be 'Konosuba'. It has a young male lead in an isekai world, though the tone is more comical compared to what we might expect from the given title.

It depends. If you like visual novels and are interested in the story of 'Your Lie in April', then it's worth it. It may provide additional content and a different perspective on the characters and their relationships. However, if you're not into the genre or the story, it might not be for you.
