bash loop over two files and one file has two key values

This is file1:

line1
line2
line3
line4
line5

This is file2:

value: line1
id: 12
--
value: line3
id: 20
--
value: line10
id: 22
--
value: line14
id: 8

I want to do this:

compare the two files and if the second column of value in file2 doesn't match the file1, then show the value line and id line

The expected output:

value: line10
id: 22
value: line14
id: 8

These are my failed attempts:

#!/usr/bin/bash

for all in "$(cat file1)"
do
    for ids in "$(cat file2 | grep value | awk {'print $2'})"
    do
        if [ "$all" != "$ids" ]
        then
            echo "$ids"
        fi
    done
done
