Hi, I don't think they strictly rhyme, they have different weights
-- for' -Ev^r
-- to' -ghEth^r
Of course, if you use them in a song, you might adjust the weights with voice, provided that the overall metric count of the phrase ending in "forever" would be such, that when you arrive at "together", its weight is somehow expected.
I have been on the Sun - it was like heaven
I wonder why this hasn't been forever
cause nothing - I think - is going to sound better
than melting with oceans of stars together
