Yuki Sumi

"I'm not gonna let you do that though. I'm gonna fight to get all the attention for myself. I hope you won't hold that against me."

Yuki Sumi (ゆき) is a character in Oshi no Ko manga series. She is a fashion model and she was a participant in the reality dating show "LoveNow". Initially imagining she'd fade into the background, she used her character to create drama and interest. From her participation, she established connections with her fellow participants, most notably, Nobuyuki Kumano (her now-boyfriend), Akane Kurokawa, and Aquamarine Hoshino.

Appearance
Yuki Sumi sports long black hair, a high school uniform, and was seen wearing a casual outfit at the ending of LoveNow.

Personality
Yuki Sumi describes herself as timid, not one who pushes to stand out, and someone with average conversational skills. She's also quite competitive, as seen with her conversations with Akane Kurokawa, wanting to gain all the attention for herself.

In contrast to this, she's a reasonable and well-meaning person. When injured by an agitated Akane, she understood her struggles and forgave her. Often she engages in regular girl talk, discussing similar interests with someone or more people.

Story
The face of the agency Yuki Sumi works for never turns down a job offer on principle, leaving Yuki with little work throughout the year. This leads to her getting an offering by Kaburagi Masaya, offering her a gig at a reality dating show. She saw this as a godsend, as she now had work to do and could potentially experience what love is.

In the show, she used her caricature to create interest, opting for stunts such as quitting the show and indirectly causing drama between her and Akane.

After an incident that almost leads to Akane's suicide, she along with her colleagues, collaborated together to save her reputation. After this and when the show ended, she established a relationship with Kumano Nobuyuki.

Relationships

 * Kumano Nobuyuki: Her boyfriend after the ending of LoveNow.
 * Aquamarine Hoshino: Yuki Sumi's colleague. They expressed pleasantries and explained one another's predicaments, such as Aqua's previous love (that being Ai Hoshino) and Yuki's participation as being for experience. She concluded from their talk that Aqua was a good person and considered giving him a kiss in the end. After the project that saved Akane's reputation, she saw a side of Aqua she never saw; when Akane played Ai Hoshino. She expressed her delight with Mem-Cho after witnessing him blushing from Akane's acting.
 * Akane Kurokawa: Yuki and Akane were described as polar opposites; Yuki having traits and skills that Akane could never have. In a turn of events, their differences ultimately lead to them getting closer to one another. Akane expressed these frustrations while Yuki took them in and understood her predicament. Their growth shows when Yuki slapped and stated her worries; never wanting events to escalate to the point they did and was open to talking.
 * Mem-Cho: Yuki and Mem-Cho were always seen discussing pleasantries and similar interests. It is yet to be known how genuine Mem-Cho was, as she hid behind a facade to save face.

Trivia

 * She expressed her liking towards Labradors.
