age gap - teacher x student

The beautiful Mio Saeki seems like a quiet young lady but when she's in the Japanese prep room she acts like an old man, eating squid sticks and talking about horse-racing. Only her teacher Shirokawa knows her true nature and despite his slightly sadistic teasing, they get along so well that she finds herself falling for him.

"You're so cute, Hinano..." His face and voice, so different from usual... My teacher slowly pushed me down, as if he's only teasing me…

Takayama, a teacher living his teacher's life "going on with the flow", is being scolded for his lazy attitude by Fuyuno, the most talented female student in his grade. In fact, Fuyuno has special feelings for Takayama...? Can the forbidden love between a teacher and a female student be avoided?
