S1·E1 Doing It for the First Time?

As Kouta is walking to school, he meets up with Chizuru who hugs him close which embarrasses him due to her breasts pressing against him, and the fact that others can see what is going on. The class representative of Kouta's class, Akane Asahina, attempts to interfere, though cannot fight Chizuru's persistence. At school, Chizuru hands Kouta a love letter, asking him to come to the music room. This reminds him of earlier in the school year where a similar event took place. Back then, Chizuru confessed her love to Kouta and in the process accidentally revealed that she is actually a kitsune. Chizuru's younger brother Tayura soon interferes and tries to tell them that their relationship is dangerous. Chizuru possesses Kouta for a little while and Chizuru conjures up a huge flame which blasts Tayura outside, leaving a gaping hole in the school building.
