25-sai no Joshikousei, Episode 12 English Subbed

Once most students are done with high school, they leave and never come back. However, at 25 years old, Hana Natori finds herself in the role of a student once more at her aunt's request. Since Hana's cousin, Kaho Miyoshi, refuses to go to school, her aunt begs Hana to take Kaho's place, since the two of them are practically identical. But as luck would have it, she is recognized by Okito Kanie—an old classmate from her days in high school—who is now a teacher! With her cover blown, Hana assumes Kanie will expose her secret. But when he suddenly kisses her, she soon learns he has other ideas. 25-sai no Joshikousei, 25岁的女高中生, 25歳の女子高生, 25세의 여고생, The 25 Year Old High School Girl
