Nice!

But - two lines are missing, the ones that would be first to be printed alone.

And, if you reverse the order of the files, you get
Code:
111 aaa
222 bbb
ddd
eee
fff
 
333 ggg
444 hhh
jjj

If you printed $line2 prefixed by a <TAB>, like printf "\t%s\n" "$line2" and printf "%s\t%s\n" "$line1" "$line2" , result were
Code:
111    aaa
222    bbb
       ddd
       eee
       fff
    
333    ggg
444    hhh
       jjj

Try this corrected version of MadeInGermany's proposal:
Code:
while   read line2 <&4
        e2=$?
        read line1 <&3 || [ $e2 -eq 0 ]
   do   if [ -z "$line1" ]
          then  printf "\t%s\n" "$line2" 
                while read line2 <&4 && [ -n "$line2" ]
                   do printf "\t%s\n" "$line2"   
                   done
        elif [ -z "$line2" ]  
          then  printf "%s\n" "$line1"
                while read line1 <&3 && [ -n "$line1" ]
                   do   printf "%s\n" "$line1"
                   done
        fi
        printf "%s\t%s\n" "$line1" "$line2"
   done 3<file1 4<file2
aaa    111
bbb    222
ccc
ddd
eee
fff
    
ggg    333
hhh    444
iii
jjj

Still open: correction for done 3<file1 4<file1
