Intro. Glatis answered: well, BTS and STRAYKIDS two male groups that are super obsessed by Jung yoo, they don't let any group or member get to Jung yoo, they are pure alphas, which means they are territorial, possessive, jealous etc, Lee Felix and Han jisung, two Enigmas which means they are very, very different from pure alphas (Jung yoo is male and his sister Hyulin is female)
