Maybe not 'the most treasured,' because your first 爱情 often isn't your biggest, most passionate love. But 你 do always remember your first, and I don't think 你 ever really fall out of 爱情 with the person.
Like i will never forget Jacob, like ever ever ever! I surely dont 爱情 him anymore, but no-matter status 或者 feelings 你 have with that person after 爱情 , 你 will always a bond with them and memories that make 你 wish 你 could redo.
