Over time, due to Fuutarou noticing Nino's other side as a caring sister, she began to accept him. After knowing her sisters' acceptance to Fuutarou, she defends Fuutarou against her father.[32] Nino is the only sister who rarely calls Fuutarou by his first or last name, using "you", "that guy", or other third-person nicknames. Despite the harsh treatment he gets from her, Fuutarou cares her just as much as the others and is always ready to help her when she's in trouble, even willing to "call" Kintaro, knowing that Nino wanted to see him.

Fuutarou tells Nino about Rena, their past, and today's encounter with her to Nino.[33] Through her interactions with "Kintaro" and later Fuutarou as himself when they were alone, she realizes the reason for her hostility was that she was rejecting him due to his status as a mentor, not for his character or him "disrupting their family."

After Nino had initially confessed to Fuutaro, she often tries to get close to him as much as she can, including taking the same part timer job after the Nakano quintuplets decided to no longer live with their father's guide. She confesses to him again since he did not hear her the first time and admits that while she has not given him a reason to return her feelings so far, she would make him notice her. Since then, Nino has become much more flirtatious and direct with her feelings. She now refers to him as "Fuu-kun", much to Miku's displeasure.

Due to Ichika's actions, Fuutarou almost doesn't think Miku holds romantic feelings for him and believes Miku supports the idea of him hooking up with Ichika. But he wants to ask what's the meaning of Ichika's whom he believes to be Miku's action on her because Fuutarou still feel vague about it.

Fuutarou later realizes and admits to Yotsuba that Miku does have feelings for him. In Kyoto, Miku gives Fuutarou some bread and is the first girl who Fuutarou talks about his mother to. When Miku confesses to him by pointing to things she likes around them before pointing at him, he smiles and replies with "I know." Before he can say anything further, Miku diverts his attention that she also likes her sisters, who were behind him watching the whole time. She playfully teases him about what she could have meant by saying she likes him, to which confuses him. Despite Fuutarou's confusion, Miku is confident he knows what she meant.

Itsuki Nakano

Itsuki is the first of the quintuplets that Fuutarou meets and quickly had a quarrel with, leading her to reject him as the sisters' tutor early on. Due to Fuutarou's consistent efforts, Itsuki began to notice the change on her and the sisters.[46] Itsuki usually compares her father to Fuutarou due to her mother's words.[47] She and Fuutarou develop each other's character, as they both overcome their stubbornness.[48][49] She knows more regarding Fuutarou than her sisters, being aware of his family's financial situation and is the first one he disclosed part of his past to. When Itsuki has a fallout with Nino due to Nino rejecting Fuutarou's efforts, she stays at Fuutarou's apartment due to her sisters not knowing where it is and she had nowhere else to go. During the Scrambled Eggs Arc, Itsuki is revealed to feel that their relationship is no longer that of partners, but to that of friends. When Fuutarou accepted this, she was overjoyed and quickly ran to the mixed bath he was in to join him, before being embarrassed.

However as things went further, Itsuki slowly started to develop her feelings towards Fuutarou. Out of the sisters, she is the one who is most interested in his past. Later, she was revealed to have disguised herself with her childhood hairstyle and using the twins' mother's name, Rena to fool Fuutaro. She did it twice, the first one to learn more about Fuutarou and the second was because of her concern to her and his feelings towards the trip to Kyoto. But Fuutarou had learned about the truth of Rena during the second attempt, scolding Itsuki (yet, still calling her Rena) to stop playing around to be in the disguise as he had become tired of the quintuplets disguising habit to get in close to him. It is revealed she does know that the sister Fuutarou met five years ago was Yotsuba, but kept this from him due to Yotsuba's wishes.
