Different Shikkie Characters have different male types like: Alpha, Beta, Delta, Gamma, Omega, Sigma and possibly even Zeta. Out of the seven different male personality types I must say that our dear Han Seonwoo from Soundtrack #1 is a Beta male…….I think every single types of the good and the bad. Positive traits about Beta males are these few things: Compassionate, Cooperative/Team players and even empathetic however some negative traits I could think of off hand would be something like coming off as a doormat or a pushover……If Alpha males are more of a leader but Beta males are more of a follower……
