Both Crime Dramas deal Cold Cases or Unsolved Murders From The Past.

Two Male Main Leads are Police Officers - Older and Younger partners.

Light to Heavy Bromance

Older is Cool n Social, while younger is Cold n Not Social.

Main Leads are SUSPECTED at some point, can't really tell whether they are GOOD or EVIL initially.
So as the story progresses, IMPRESSIONS on them KEEP CHANGING.

In the end, Younger one learns EMPATHY in the company of older.

Older one is suspected to be a murderer of his ex partner in investigation.

Similar to both season one and two of Papa & Daddy (and also from Taiwan) with taking care of a child, though Papa & Daddy it's an established couple.

Similar to FC Soldout in that it has a sport element; however, the sport is not really the main focus, the focus is on the relationship.

The side couple in Love at 7-11 has a similar plot element of taking care of a child. I don't think there's an official international release with English subtitles though.

HIStory 2: Right or Wrong has a similar plot element of taking care of a child including making meals.
