He married to one women in the end but the novel is also tagged as harem so I'm assuming there's other girls that will show up in a 'romantic-ish' way. Take my words with a grain of salt because I'm not actually sure if there's a proper harem in the novel and I'm just basing it off on the tag but I can say for sure he married a woman at the end.
Based off a novel and yes, there is romance. Lin Fan got married in the end for real. I just skimmed through the mtl of the novel so I can't really say for sure if the harem is unbearable but it's there. Not sure if the manuha will stay loyal to the novel but if it does, then there will be romance.
