[Year-round] I was possessed as an extra in a novel (Nam Joo Mi-jeong)

Season 1: I'm just an extra in a novel, possessed by someone else. Hmm...? But I'm just an extra with no connection... Why am I entangled with the female and male leads? It's an exciting story! Shall we watch? Season 2: 7 people come to the real world? No, 8 people! Yeojin has lost her memory... Will she be able to regain it and recognize the eight people? Please show lots of love for Season 2 as well~
