i just can't take her seriously. we've spent about 15 chapters just letting her do whatever she wants for dramatic effect when all they need to do is NOT let her do anything.
All this "hidden plot" thing is just too stupid to tolerate and the author using it to try (and fail) to add some unnecesary drama is ridiculous. In this chapter the author even tried to give Tenshi more background to instigate some simpathy on the readers. Didn't work. Just kill Tenshi and go the easy way to give us a few chapters of silly romcom. Then end it with Jindou end, Ayumi end Harem or Yuri. At this point I expect (nit don't want) 2 things: Tenshi alive and open ending.
This manga trying so hard to be dramatic is way more work than the author can manage.
