Oh like the Bollywood movie Action Replay!
"Action replay" was actually remake of 80s Hollywood movie "back to future" both are good in their own way if seme did any slight change in past jd wouldn't have born
So Back to the Future kinda? I don't think sensei would wanna copy it too much. She already ran with the kinda weird drama from that movie where Marty's mom thought he was hot cuz she didn’t know that would be her son. Even so, I love the use of that inspiration, as messed up as it is. She made something unique for sure
Imagine if the plot was slightly different? Like ryou went back to the past, became friends with his father and taught him many things so when konomi finally met his mom, they'll be able to love each other and in result, will not get divorced. Ryou will grow up with a whole family then many years later, konomi will realized the friend he made when he was 15 years old was his son. Omg that would be so sweet but the author want some forbidden love i guess
