- Near the end of the final season, Miyuki has just walked away from the scene of an accident to find help after she and another car fall off of a cliff, and passes out from exposure to the rain, her own injuries, and exhaustion. She then has a dream where she meets Ken on the roof of their precinct building and he proposes to her. She wakes up to find Ken who, despite having a broken arm, is carrying her to safety on his back and begins saying the exact same words as Miyuki heard in her dream. She says yes.
- Even earlier, during Sena and Daimaru's wedding, there's the scene where Ken is supposed to get a kiss on the cheek from Sena after winning an impromptu race. He atually gets one from a Miyuki who, upon Sena's request, has put on the wedding gown and poses as the bride.

Natsumi: (softly) "I love you, Toukairin." <cue Big Damn Kiss>
- Natsumi clocks out early so she can get to the airport in time to give Toukairin a piece of her mind, for throwing their last arm-wrestling match, and for leaving without telling her how he feels about her. She barely lets him get a word in edgewise, 'til he stuns her with a "Shut Up" Kiss. Natsumi recovers a few moments later, then says it herself.
- Any time Nakajima's actions prove his feelings for Miyuki, most notably taking a shot for her, twice.
- In season 3 when they find a little girl who mistakes the Chief for her recently deceased father, Natsumi arranges for her and the Chief to take the little girl out for a trip so that she can be with her "Papa" one last time.
- During the final episode of the final season, after hearing a joke from Natsumi about them quitting the force and getting married, the three kids (Yuta, Sho and Maho) all come to the station to plead with them not to do so.
