I wish at the part in Death Note where L and Light have their tennis match and the teacher wants them to join the tennis team that he successfully convinced them and the whole story just abruptly pivoted to a sports manga
the kira killings stop the moment light joins the tennis club and it becomes obvious to everyone that light was kira but L doesnt want to lose their top player right before they go to nationals so it abruptly pivots back into trying to fool the police again
