Your & My Secret 4 features story and art by Ai Morinaga.

Senbongi is acting cold while Akira seems to be getting along with Shiina with no intentions of switching back. Akira gives Momoi the OK to go out with a guy (or at least hold hands!), rubbing in the fact that she has no feelings toward him. Fed up with it all, Momoi agrees to go out with Senbongi and discovers that, to his surprise, he actually kind of likes it!
