Blue Heat Makes the Flowers Bloom -the Night I Was Turned From a Teacher Into a Woman-

Official English Translation: Renta!

Official Korean Translation: Lezhin

Haruna, a new teacher at a prestigious boys' school, starts getting hit on by one of her students, Yoshitaka Ai. Haruna is shaken by his single―minded pursuit of her, but she turns him down because he is her student, and because there is a 15 year age gap between them. Time passes, and it's the day of Yoshitaka's graduation. The graduation ceremony ends, and the two of them bid each other farewell at the school gate as student and teacher. The moment Yoshitaka sets foot outside the school gate, he says to Haruna, "As of this moment, I'm no longer your student. I will never use the word 'teacher' with you again. I'm a guy who's been in love with you for a very long time." So what will Haruna do now that the taboo surrounding the idea of a relationship between teacher and student is broken?
