The only shounen I’ve ever read lol

http://www.mangago.zone/read-manga/code_breaker/ this ones rlly good and theres a bit of romance that is developed nicely

Welll, the one that is more like shonen is Jojo, but is a commitment to read. Other seinen manga that are great but not really shonen like: Berserk, Arte, Stigmata (the sequel is BL), Loplop and Coffin Jackson.
Annd this one is more like shoujo/josei but is soo underrated its hurt, give it a read pls http://www.mangago.zone/read-manga/gorae_byul_the_gyeongseong_mermaid/
Can you guys recommend me some non harem shounen manga that's not mainstream yet. I like action with a hint of romance but honestly anything is fine as long as it's not a harem.
