I really need suggestion for a loyal Male MC in other words NO HAREM. Pack with action, but the female MC not just there for the sake of romance tag, but actually have a good active role in the novel. I have done my own series finder, but i guess i dont find much. So really need your help.
+1 this thread. I'd like that too...Though I could recommend Andur from Royalroadl....His novels are usually involving one male and one female mc...
Coiling Dragon ,perhaps. FMC did accompany MC for a lot of chapters and even to the next higher realm.
You'd probably be looking at all those transmigrated empress/consort novels where the male lead is heads over heels for her and usually having some other admirers.
http://www.novelupdates.com/series-finder/?sf=1&gi=15&mgi=and&tgi=593&mtgi=or&sort=abc&order=asc At least 1 of these novels could have what you're looking for.
Undefeated God of War ( very close to your description ) Ze Tian Ji ( many chapter laters to MC and his girl to reunited) Douluo Dalu ( beware that this novel has tragedy)
Duoluo Dalu? Not sure about the Female active role.. but can be sure that male MC loyal toward female
Undefeated God of War mc is like....100% dedicated to female mc but she isn't really by his side for the first 377 chapters at least since that's where i've read up to. she does make appearances sporadically in the story though, just not by MC's side for now. mc is making an active effort to get to her side however
God of Cooking. Not your standard story, but if you're looking for loyal romance and don't mind the fact that it's only barely a fantasy story because of 1 minor element, here's your not-fully-translated-yet novel. Adorable as all hell.
Knights & Magic - There seems to be only one romantic interest for the MC. For example, a princess appears later on but is shipped with his friend instead. Magi’s Grandson - Only one romantic interest. New Game Plus! ~The Struggles of a Popular VRMMO L... - It *seems* he's going to be loyal to the romantic interest... But it might be too early to tell for sure. The Noble Girl Living in Debt - This one might be considered romance? If you're ok with harem provided he actually cares about them... You might want to take a look at Mushoku Tensei.
