    In any case!!! Hoping they do well ♥♥ + gugudan fighting!

  • Isabelle

    I think that Sejeong is the visual in this unit, as she was the only one that ranked in the top 11 visuals in p101, but they’re all really gorgeous

  • Vera

    the name feels like a combination of just mina and sejeong’s names .. what does the name mean? (as its also the name of their song?)

  • Lily Perez

    Se- Sejeong
    Mi- Mina
    Na- Nayoung

    Saemina means jealous in Korean

  • Lily Perez

    They’re not the 3 most popular, Sejeong and Mina are but 3rd most popular is Hana

  • Lily Perez

    She is the leader it was confirmed on “Gugudan Semina in 10 seconds”

  • Vera

  • morgan

    they’ve mentioned on weekly idol that the name doesn’t mean anything other than a combination of their names 🙂

  • Mr. Park Jimin😘❤

    Pls add to kim sejeong position as visual because she is rank 4 in top 11 visual of pd101


    Fyi, in this sub-unit nayoung is the main vocalist it was mentioned on idol room before

  • Mona

    I miss l.o.I

  • felipe grin§

    SeJeong isn’t a visual
    the visual line is integrated by Hana, Mimi and NaYoung
    NaYoung would occupy the position of visual in SeMiNa
