This drama is verrrry slow moving and frustrating. The characters are all unlikable except the ex boyfriend's boss. The teen ml is a stalker and pot stirrer causing more trouble than anyone with a right mind would allow in their life. He's hot for teacher and anyone against it be damned. Mom of ml is a psycho that needed to let her grown baby boy go by 18. And the fl is so wishy washy and weak with a do gooder attitude, yet she's simping over a minor for years. Like make it make sense. And how is this woman still teaching after all the events that transpire in this story?? She must have 9 lives when it comes to her dream profession. Absolutely ridiculous! Also, exactly when does the "love" of this couple blossom? From what? A hard slap (Akira slaps teach in one of their first encounters and she never reports it), a shared proclivity to take bad pics of sunsets on their phones, reciting a random poem, or was it the many many sensei wrist grabs whilst running away that the ml does?? Your guess is as good as mine.
I've watched dramas and movies with this taboo teacher/student plot before so it's nothing new to me, but this one was overhyped and just not good.
