Nina's Links
Nina is the one who trained up Yooni when she first joined the maid cafe. She will often refer to her as 'senpai' but says it in a joking manner and Nina will often laugh and try and change the subject in embarrassment.
They've become quite good friends since working at the cafe and are often seen hanging out outside of work. Nina loves to make desserts and Yooni will often try and help her make them where she can and Nina will give her many sweet treats to trial when she makes them for the first time due to Yooni's very sweet tooth.
