25 Sai No Joshikousei Season – Episode 1

Natori Hana, a 25-year-old sweetheart with a kind heart, finds herself in an unusual situation. Her careless cousin doesn't give two shits about attending high school, so Hana steps up to the plate and takes on her cousin's responsibilities. On her very first day at this new gig, she accidentally stumbles into a class from her old days - yep, you guessed it! She runs into Kanie Akito, an ex-classmate who just happens to be teaching world history at this high school now. And guess what? The whole ruse of Hana pretending to be her cousin falls apart like dominoes on the first day itself when good ol' Kanie catches on!

But it doesn't stop there, oh no... Natori Hana is going to have a wild ride filled with unexpected encounters and sizzling chemistry. She might even end up getting tangled in some forbidden love affairs - all while trying her best to keep up with the teenage life she never really lived!
