The similarities :Both of them have a child of the main lead going to the past where the parents are in high school.both the parent characters r bad in studying and they help them with their studies.
Both of the future child ends up falling in love when they're in the past .both r cute and heart warming stories .both the child lead tries to make their parents fall in love with each other .

The differences: in TW the main lead is a guy whereas in idwtbfwu it's a girl lead.
In TW there's two characters that's travelling into the past making their love story a bit easier .since they can still be with each other in the future .
Whereas in idwtbfwu the girl lead falls in love with someone in the past .that makes their love story a bit more complicated .

I finished idwtbfwu and it's a beautiful story . totally recommend it
