In Volume 2, she secretly was stalked by someone. Personally, she is my favorite among the girls. When she spoke face to face with her stalker, she outright said to her stalker that she always suffer from diarrhea and when she met a handsome guy, she would go home and m*sturbate. So stop putting her on a pedestal as the person on the stalker's mind and the real Nanase are to different person. She started to deeply fall for the MC after Chitose was beaten up by the Yan High delinquents. Chitose helped her solved her stalker problem and her past trauma. Though she supports the other girls, she knows she is a horrible person as she knows her chances are too high.

In Volume 3, she had a dilemma either to stay on there city (Fukui University) or go to Tokyo because she is filial daughter to her very strict parents, especially his father who wanted her to stay. She is the most stack heroine as she didn't only took the role of a Senpai figure, she is also secretly the childhood friend of Chitose and his first love and heartbreak (She didn't reject the MC, it was a misunderstanding between the Grandmother and Chitose because Asuka was describing Chitose and his Grandmother thought it was another kid that Asuka has a crush with.) Though Chitose helped her realize what future she wanted, it was still Asuka who did most of the work to convince her father to allow her to go to Tokyo U by doing research as she knows she isn't as convincing with words like Chitose. Chitose push her so she could stand against her father. Though she knows her strength, she also understand that among the heroines she is also the most vulnerable for she is a year older than Chitose and friends so unlike the other girls she can't hang out with Chitose and if Chitose loves another girl or she got rejected, she would have the hardest time to bounce back. We learned in Volume 3 the true meaning of the title.

In Volume 4, Haru is extremely talented in basketball but she is extremely short. Though she is talented, the lack of height always pushed her to train harder than anyone and when she became the basketball captain she also pushed her teammate to train as hard like her which made them reach their breaking point. This Volume also gave a crucial understanding of the Chitose's past and why he left the baseball team. It was Haru who convinced the MC to help the baseball team after learning what happened and how he still love the sport. She deeply fell in love with Chitose after she saw how Chitose loves baseball like how she love basketball and how Chitose raised the gift that she gave to him after a home run. It is also cute when she tried to kiss Chitose's lips but because she was short, she only manage to kiss his neck.

Volume 5 is a game changer, it actually pushed the story and her action affected not only the story but the characters. Everyone treated Yuuko as someone special, everyone agreed to her, the only time someone was against her and scolded her in front of the whole class was Chitose. The Volume 5 start as usual and on the middle part where they have fun in the beach but the last chapter of the Volume, Yuuko confessed to Chitose. It was already hinted but when Yuuko spoke out her feelings to Chitose, everyone (Team Chitose) was there, at first everyone thought it was a normal flirting banter but Yuuko made it clear that she wants answer. Chitose actually likes Yuuko, he immediately list everything he likes about Yuuko on his mind from the biggest to the smallest but he rejected her in front of their friends. It didn't only broke Yuuko, Chitose, but the dynamic of Team Chitose's relationship. Even Yuuko's mother who was introduce on Volume 5, agreed with Yuuko that it was idiotic for her to do it but like me when reading, her mother was proud of Yuuko.

In Volume 6, deals the aftermath of Yuuko's confession to Chitose. It shows Chitose broken after rejecting Yuuko's feelings. Though her best friend is Yuuko, she decided to console Chitose first which would be delve deeper on the chapter. It was explained in this Volume how Yua fell to Chitose. Yua originally hated Chitose as he is the only one who sees her fake smile that she wasn't fine. Her and Chitose bonded after Yua learned that Chitose and her is not that different. Context, Yua's mother was a musician and she passed this love for music to her daughter but her mother left like left without any sign leaving her, her father, and her brother. She was the first one to go to Chitose's house because he showed her that what she perceived about him was wrong. Chitose also reinforced her loves for music. She became like a mother/wife to Chitose. She is a constant resident to his house, cooking and buying groceries with him.

He punched Chitose after he rejected Yuuko (FMC 4). He likes Yuuko (FMC 4), he would express his feelings to Yuuko in Volume 6 after Yuuko confessed to Chitose. Though Yuuko loves Kaito, her feelings for Chitose just dwarf in comparison to her romantic feelings to Kaito.

He likes Nanase (FMC 1), after he saw Nanase bloom when she express her feelings for Chitose. But, he immediately understand that is is impossible between the two of them and he was not the hopeful type. He made this confession to Kenta after what happen in Volume 5.

He is more of tsundere type, he is the one who helped Chitose to train when he decided to help the baseball team. He also helped Chitose again when he was down after rejecting Yuuko (FMC 4)

She is the only character that made the 4 heroines cried {Nanase (FMC 1), Asuka (FMC 2), Haru (FMC 3) & Yua (FMC 5) }. She took the special place of Asuka, she took Haru special position, and Yua's special place&position, while she destroy Nanase with her words. Nanase was greatly affected by this; making her became even more bold and even seduce Chitose on doing "IT" with her on his house. Kureha actually cried when she learned that Yuuko (FMC 4) was rejected, Yuuko has became more mature in Volume 7-8. I like how the two most comforting character Asuka and Yua get along extremely well. Nanase is also changing not caring for Haru's feeling in basketball after Kureha destroyed her (Nanase). Chitose already made his decision to confess whether he like Nanase or not next cherry blossom.
