Jina (J/oy and N/ina) is the friendship of Nina Martin and Joy Mercer. These two characters began as frenemies since they are fighting for the affection of Fabian Rutter. They really hit it off when Joy disguised herself as Nina, and kissed Fabian. Nina seemed to have walked in, wearing the same dress, with the same hairstyle, and Fabian had no clue. They both liked Fabian so they began fighting over him. The two girls first met in the very first episode of Season 1, when Nina bumped into Joy, Patricia, and Fabian, while walking to the school for the first time. They did not meet again in person until the end of Season 1. The one of the only times they were in touch Joy and Nina look at the Mask
was when Sibuna chatted with Joy under Victor's supervision on a computer. Nina didn't talk much though with Joy. They are currently friends after the finale when Joy and Fabian officiall became just friends. Both are thought to be Paragons. But Joy wasn't the real paragon Nina was the real one because Nina was born before Joy on the same day and Nina was born on the chosen hour so that causes Nina to be the Parogon/Chosen one. Both of the two girls had the same birthdate Nina was born at 7:00 am at July 7 while Joy was born at 7:00 pm. In Season 3 Joy was upset when it was revealed that Nina wasn't coming back and in Season 3 she kinda tries to kinda get closer to Fabian to do stuff Nina would get jeolous by. So if Nina never left then they would maybe become frenimies again but if Joy didn't try to get closer to him because shes only trying to make him feel better about Nina and Nina never left then they would still be friends. They care for each other, and don't fart in each other's rooms, but since Joy is now dating Jerome they likely won't be frenemies again.
Nina and Joy, begin a romantic rivalry triangle as they compete to win over Fabian's affection. In one of the episodes, Fabian tells Joy to drop the article about Senkhara, but she tells Fabian "Kiss me. If it means that much to you..." Fabian leans over to kiss her, but then backs away and admits he still loves Nina, who hears from behind the door and becomes very happy. Joy, seems very jealous of Nina in Season 2 as Fabian gets closer to Nina. Joy desperately wanted to date Fabian, but he
Joy wrote a vicious article about Nina, criticizing her for skipping class, suggesting that her scholarship should be revoked, and criticizing her for not having her grandmother flown home when she got sick. Joy apologized to Nina for writing that article, but she doesn't seem to mean that because she tells Patricia that she wrote the article, so Nina would get the idea and go back to America. She believes that Nina stole everything from her and that Sibuna shunned her after Nina came. Patricia defends Nina, and tells Joy that Nina never stole anything from her. Joy is very jealous of Nina, and she and Patricia's argument culminates with Joy telling Patricia that she didn't need her anymore. An angry and annoyed Patricia leaves the room. Joy starts crying after that, pained from losing her best friend.
Joy agreed to work as a strategist for Fabian in the Sennet game and seemed to be genuinely concerned about
getting Nina back, despite their rivalry. She also got extremely angry when Amber expressed concern that she would throw the game on purpose, so that Nina would stay trapped. She insisted that she would never do something like that, despite not getting along. At the end, Joy helps Sibuna and reconciliates with them (becoming Patricia's best friend again). Nina also started crying from guilt after almost killing her.When Fabian offered that Joy can help Sibuna looking for the key (from Trudy's vision) while Amber makes a face Nina agrees.
She hugs Nina at the end. She helps them get the Mask of Anubis and helps Nina and the others escape. Joy tells Fabian to aks Nina out, and she is happy when Fabian and Nina get back together. Now Nina and Joy are good friends. Joy has given up on her crush on Fabian Rutter, though because of their close friendship, during the finale, threw herself at Nina's fire blast and nearly died. At the start of Season 3 Joy was annoyed that Nina was not returning.
