1x12 - Ms. Koizumi Loves Ramen Noodles

While heading home from Osaka, Yū ends up stranded in Nagoya after seemingly spotting Koizumi from afar and hopping off the train. With only 500 yen on hand, Yū goes to a fast food ramen shop, where she thankfully runs into Koizumi. Later in Autumn, Koizumi catches a cold and ends up taking several days off school, her continued absence taking its toll on Yū. After Koizumi eventually recovers, Yū decides to leave her alone to let her enjoy her first ramen in weeks.
