|Kanji||皆川 由紀（みながわ ゆき）|
|Relatives||Unnamed Older Brother|
|Friends||Jun Furuya (Boyfriend), Saki Kanda|
Yuki is a slightly fair-skinned girl with long pinkish-red hair that she usually has in straight bangs, green eyes, a charming face and her appearance resembles a sleepy person and she is fairly tall for a girl.Whenever Yuki plays tennis, she wears her hair in a ponytail with her bangs out a white t-shirt.
Yuki is an extremely positive and nice girl with many layers to her personality. Always seen grinning, she says that she is a lazy person. She is popular with boys and has many friends. She is also very intuitive, as she instantly knew that it was Hotaru Furuya on the phone rather than Jun with a single text and knew Hotaru would follow Jun to their "study session" and appropriately ordered three sundaes in preparation.
She is very brave when it comes to romance, and immediately makes it clear that she is interested in Jun Furuya, repeatedly saying that she likes him. Likewise, she is a very supportive friend as she often tells Saki to simply go for it when the latter asks her for relationship advice. She herself is also assertive, confessing to Jun very early in their relationship, and making it clear she wanted Jun to kiss her again after their first time doing so. She takes the initiative very often, grabbing Jun and kissing him when he is initially reluctant to kiss her again and being very physically intimate, often curling her arm around his. Furthermore, she is incredibly patient, waiting several months for Jun to reply to her confession and agreeing to go out with him despite how long he made her wait.
Yuki is also shown to be very defensive of others at times. When Jun is mean to Hotaru, Yuki immediately comes to Hotaru's aid despite Hotaru's blunt disapproval of her brother's relationship, stating that Hotaru will become her sister if she and Jun ever get married and as such, Jun will have to be just as nice to Hotaru as he is to Yuki. Additionally, when a group of older men attempt to harass Hotaru on the street, Yuki rushes to Hotaru's aid and helps her escape the situation.
Perhaps her most notable trait is her love of joking around with others. In nearly every scene she is in, she is shown messing with other characters, typically Jun and Hotaru.
Though she is often teasing others, she is shown to have a timid side. She is often afraid of men and was too scared to speak when a group of men cat called her on the street. Despite often joking around with adult topics, she gets extremely flustered and covers her face when things get romantic with Jun. Likewise, when Jun first kisses her, she shakes rapidly and blushes hard before they actually kiss. Afterwards, she is still incredibly flustered and asks him to treasure the kiss since it was her first.
Jun is Yuki's boyfriend who have been dating for around half a year. She likes to be spoiled by him and she likes how serious he always is that they were both each other's first kiss.
Hotaru is Jun's younger sister who has a big brother complex and she dislikes Yuki because of that. Hotaru often says that she hates Yuki and tries to get them to break up. She thinks that Yuki is tricking her brother and that she actually has a nasty personality.
However, Yuki really cares for Hotaru and wants to get closer with her. This may be due to the fact that Yuki also has an older brother and she was also worried whenever he got a girlfriend.
After a while of being with Yuki, Hotaru seems to be gradually accepting her and begins to think that she isn't all that bad.
Yuki knows that Hotaru is possessive of her brother and often teases her by intentionally showing her how much they love each other.
Saki is one of Yuki's closest friends who are both in the tennis club and they are often seen with each other. Yuki knows that Saki and Haruhiko Takase like each other that she tries to help them get together.
