Both dramas are heavy and emotional which focuses on family relationships. Go Ahead has more comedic and romantic sides while Beautiful World has mystery and school stuff.

In both cases, a child experiences some traumatic events (rape leadingg to death in Higashino Keigo'Samayou Yaiba' and being pushed off a roof and paralyzed in 'Beautiful World'), and the parents are seeking justice.
Both are heartbreaking but Higashino is way darker.

Both drama series are set in a high school and feature students as protagonists.
Accidents happen, but in reality they are not accidents.

Similar. Student is injured. You find out why. It is also about school violence and likewise the parents get involved. Trying to cover it up but the truth comes out! Recommend

both stories speak of the anguish and sadness of parents when their children have an accident.
