Yikes, Chika got called out as a rival after he had gone through so much effort to jumpstart their romance to cover up his own feelings. And he missed his chance to deflect it like he usually can. Azuki and Mizuki seem so alike that I'm not sure if you can call it chemistry. I was half hoping someone would find the truth to the faked psychology test, but that moment has passed. I thought this chapter would be full of painful moments of Chika seeing the two awkwardly blushing back and forth. Unhidden spoilers abound in the main manga comments so I know what's ahead anyway.
