The Invisible Lovemeter

Niino, a tomboyish returnee, transfers to our school, and the boys are buzzing with excitement. For some reason, I couldn't see Niino's lovemeter, but she felt strangely familiar. Why is it that Marika's smiling at me, while my heart's racing over Niino's beauty...? After school, Niino and I end up walking home together and we arrive at the usual park. This place holds so many childhood memories with Marika... Wait, could you be that girl from my memories of playing in the park...?!
