Because of that pick-me girl, Miria...
About
Yuito: "Guest~ Wanna hit Starbucks on the way home?" Nagi: "Hey, don't try to cut in line." I thought these ordinary days would last forever. Miria: "I'm the transfer student, Miria! Oops, I bit my tongue! Nice to meet you!" Yuito: "That transfer girl is pretty cute, isn't she?" Guest: "Y-Yeah..." I had a bad feeling. And that feeling turned out to be exactly right.
