That damn cliffhanger was just cruel.
and the ironic thing is that Mashiro probably failed and then the scummy girl becomes the breadwinner supporting Mashiro
I can't deny suspecting this as well... Especially since she specifically only took the one exam. Scumbag at least had backups.
Looking at the phones whose case is slightly different in shade/color, the one who failed was makino
Makino's phone has two distinct buttons while Mashiro's has a unified button on the side. So it looks like Makino passed and Mashiro failed
Ehhh I think the author intended for it to be the same model phone. And for us not to be able to tell the phones apart in that last page.
Looking at them again, yes, we see different sides of the phones there, so they should be identical when shown from the same side.
