You did the right thing. Soul mates are the upper couplet, a good marriage is the lower couplet, and couplets are generally flat, that is, the last word is complete (that is, 3 or 4 sounds). The last word of the second couplet is flat tone (that is, 1, 2 tone). But all this is silent. I think I wrote this myself. Attention should be paid to the problems of leveling, leveling, leveling and leveling. This is the general traditional rhyme of couplets. Your couplets can only be printed in the front. The small one in the front and the big one in the back are good marriages.
