Port Mafia Arc
After Atsushi passed the exam to join Armed Detective Agency, Haruno later serves tea to Agency president Yukichi Fukuzawa and asks him if he truly wishes to have Atsushi in the Agency. She then spots an upright tea stalk on his tea with a smile, considering it as an auspicious sign. Fukuzawa did not answer and just drank a tea.

The Guild Arc
As the Agency, Port Mafia, and the Guild engage in a three-way war, Haruno and Naomi retreat into hiding in a safe house. They learn about a cruiser explosion near the Yokohama commercial port, which Haruno expounds to be owned by a private company. Haruno then contacts and warns Fukuzawa, thinking that the Agency might be in trouble next.

Later, Chuuya tells the agency that Port Mafia gave the location of their clerks (Haruno and Naomi) to the Guild. Fukuzawa is shocked by heard and orders them to evacuate then he sends Junichiro and Kunikida to rescue them.

Cannibalism Arc
Twelve hours before the virus outbreak on Fukuzawa and Mori Ougai, Haruno attempts to look for her pet cat, who has not returned for two days. Naomi dissuades her, though Haruno notes how Mii-chan's disappearance always preludes unfortunate incidents. Hence, worrying for Fukuzawa's safety, Haruno remarks how she wishes to look for her cat to possibly avert anything bad happening to the President.

However, Haruno starts crying and hugs Naomi, saying that she is very worried about Fukuzawa who went off on his own despite of Pushkin's dangerous virus.

The aftermath of the incident, Yukichi and Kirako together attend a banquet held by the Agency at a luxury liner given to them by Francis Scott Key Fitzgerald. When they come down the steps, the rest of the staff notice them, the employees greet them and bow.

Perfect Crime Arc
When Ranpo understands that it's hard to solve the mystery, he decides to not give up because he knows that his friends at the Agency trust him. In Ranpo's memories, Fukuzawa and Haruno shown in the same manga panel together. It could mean that both Yukichi and Kirako believe at Ranpo in the same way.

Fanon
FukuHaru is a rare pair within the Bungou Stray Dogs fandom, as the two have had few interactions with each other. The ship is not noticeable for many people in fandom as Haruno is a minor character and the pairing is often overshadowed by its biggest rival ships. The other problem for this ship can be age gap. Despite Haruno not having official age, people realize that Fukuzawa is older than her. However, there are also people in fandom who ship pairings with big age gap (especially when it comes to slash pairings) and those people have no problems with that. At the moment, their relationship doesn't seem to have a tag on AO3, but it has 2 romantic works in Ficbook.

The rival ships are FukuMori, FukuRan and FukuFuku on Fukuzawa's end while Haruno's rival ship is HaruNaomi.
