10/10 tho it is still on-going.
You can read it's novel somewhere (also ongoing with 700+ chapters). It has no romance! Yez! It has some female cast (I love them) and I think they just really admire the MC. The MC is only focusing on making money to have a peaceful life.
PS. I REALLY LOVE CALE!
8/10 and still on-going.
Based on my research, yes, it has romance. Don't worry as the MC is focusing on leveling up to avenge his brother. The FL is also not annoying, I actually love her. I kind of ship them too, tho I don't really like romance in this kind of genre. Overall, the plot is good, the romance is not really that bothering (for me), they're kinda cute.
If you wanted to read its novel, you can just search it on net. To warn you, some parts can be little frustrating
