The Strong Man From The Mental Hospital
Ch. 322 The translation is bad. A lot of panel is missing. Official translation on webcomic, the title : The Mighty Warrior From A Mental Hospital https://m.webnovel.com/comic/the-mighty-warrior-from-a-mental-hospital_21053139305014801 More ch https://snowmtl.ru/comics/the-strong-man-from-the-mental-hospital Based off a novel and yes, there is romance. Lin Fan got married in the end for real. He married to one women in the end. 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. DON'T WORRY ABOUT THE HAREM TAG, LITERALLY THERE IS NO HAREM. The only harem I could think of is the amount of people ( mostly men ) who start to idolize the duo lolol.
