Yuki Sumi/Relationships

Nobuyuki Kumano
Her boyfriend after the ending of LoveNow.

Aqua 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 kissing him 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 opposites; Yuki had 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. How genuine Mem-Cho was is yet to be known, as she hid behind a facade to save face.
