I know what asexuality means so Aromantic is sort of the same thing but on romanticism, no?

Yes

Most people outside of the LGBT community dint know unfortunately

Sexuality is something so unknown to the general public, people, most of the time, think that there are only one or two ways to love but there is an infinity, they forget (or don't know) that it's also normal not to love. Ah lalala (〜￣△￣)〜
Me too, I am not an expert in love so I won't go further on the subject!
