Why does everything Rei do is so adorable? She's so caring and sweet towards the members but then she's also a mischief 😅

they have worked hard for their debut, let's dive continue to support them, they will definitely become a popular girl group one day because they are all talented and don't care about haters badmouthing them haters are just jealous of these talented girls and even though the first time i came because of yujin and wonyoung but now i really like all the members and may i ask what is the difference between liz and rei other than their hair color? if the starship made their hair color the same i would be confused about who is rei and who is liz
