A lone 連用形 in song lyrics


The [lyrics](https://utaten.com/lyric/ac18071012/) to 魅惑劇 by ALI PROJECT
contain the following fragment:

> 叶わぬ願いは過去のもの  
>  愛する痛みは **傷を閉じ**  
>  魅惑劇

I would take the bolded 閉じ to be either continuative or a nominalization,
except in the first case there isn't any verb that the sentence/statement
could continue onto (is it perhaps just an artistic omission?) and as for the
second I haven't really encountered 閉じ used to mean 閉じること searching around on
the web. I'm also not sure whether it could be used with を in such a case.  
Is it one of the things listed or something else entirely? What nuance does it
carry?




It is continuative, i.e., so-called 連用中止 (e.g. [here](https://nihongokyoshi-
net.com/2018/12/06/jlptn3-grammar-renyoochuushi/)). A general effect is
usually explained as '余韻を残す' (giving an impression/aftereffect), but here I
suppose it can be considered simply for connecting to the third line.

A reason should be metric. Note that the first and the second line use the
same number of syllables (hiraganas).

> 叶わぬ願いは (8) 過去のもの (5)  
>  愛する痛みは (8) 傷を閉じ (5)

Looking at the lyrics, other parts seem to have a distinct pattern for the
number of syllables as well (I didn't count, so could be wrong).
