This is one of my favourite list ❤

I was happy to find a list of novels without harem and romance but the stories focus on friendship and family. I have also made a list of similar novels but the list that I made is specifically dedicated to Japanese fantasy novels without romance and harems. If you are interested, you can take a look at the following link: https://www.novelupdates.com/viewlist/52356/

This is one of my favourite list ❤

I recommend getting rid of "The Dukes Eldest Son Escaped To The Military." Read it a while back and sure, absolutely no romance and no bromance as well, did not find any characters that stuck to Jaidens side at all, and the novel is just, amateurish and boring in general. However, if you have read the novel all in itself (as I've only read up to 64 before dropping it due to it being absolutely boring with no characters I'd get attached to) and found some bromance or familial love in it, then just leave it there ^^
