gen asking this manhwa got no romance right?? there's no mc's love interest

Few girls are into him, but mc is stone cold fighter, at this point he didn't show any interest in anyone.

Thank youuu

I think he just kinda slow that what he is. I aswell thought that he was cold but after reading his past, I really think that he is kinda slow and doesn't know(〜￣△￣)〜
