S15 visited the rest of the LOVElution members in today's SIGNAL (they've already met each other!) Nien might know who she is since she pointed at her like she seemed familiar so who could it be 🤔
may (cherry bullet) mashiro (kep1er) sheon (billlie) shana (lapillus) youngeun (kep1er) kotone (tripleS) and if s15 is zhou xinyu, all of u+me team will have debuted 🥹
