The Devotion Of Suspect X (2017)

Both productions start off with protagonists trying to cover up murder. As a consequence, these deaths attract attention of unconventional police officers who try to figure out who and why killed these people.

Male leads in both productions are trying to cover up a murder committed by someone close to them.

they're both adaptations from the japanese novel. there are some differences but they are more or less the same. good/ok.
