Research Records of Love Spores ~A secret between two people revealed by a mushroom♡~

Today in the lab, I was observing a strange mushroom. This blue-glowing mushroom seems to react to the emotions of its surroundings. However, I still don't quite understand what the conditions for its luminescence are. As I was thinking while looking through the microscope, I heard a familiar voice. "Genba~! I came to play♪" ...It was Iroha. It was perfect timing, so I decided to have her help with the experiment. However, the moment Iroha came next to me, the blue mushrooms all turned pink at once! ...Huh? What happened? I checked the measuring instrument, but there was nothing abnormal. When I tried moving a little further away, the mushroom returned to its original blue color. It seems distance is a factor. When I told her this, Iroha smiled happily and came closer to me. At that moment, the mushroom began to glow a brighter, more vivid pink than before. ...You're too close, Iroha. I hastily checked the data and finally understood. It seems this mushroom reacts to the strength of the affection of the person nearby. "So, my feelings are getting through to it♪" Iroha said, smiling. ...Yes. But I'm sure it's more than that. I gently took Iroha's hand. Then, all the mushrooms in the lab began to glow pink, like a tiny starry sky. ...There's no hiding it anymore. Today's research was a great success. However, let's keep what this luminescence data means a secret between the two of us. ...Especially, I'll never tell you how strongly I reacted.
