Raina's Links
Raina works in the same maid cafe as Yooni. It was Yooni that encouraged Raina to join the maid cafe in the first place so they could hang out more outside of school. Yooni helped her a lot with her confidence and gave her lots of tips to improve. Since joining the maid cafe Raina's confidence has grown and this makes Yooni very happy and proud.
They are very unlikely friends from school, having been put in most of the same classes since Raina transferred a few years ago. Yooni took an interest to her right away and made it her mission to befriend Raina. People often look twice when they see the two hanging out together due to their very different styles, Yooni is always very outgoing and bubbly whereas Raina is a lot more quiet and reserved, but their friendship works perfectly for them and they are the best of friends.
