I think Sowon doing it naturally its mean its her real personality, i think she is a pure person. She is naturally a cute and funny or dork person. She also said that she is odd/dork person in the interview in Japan . With her cuteness, and funny personality, i think she can make male/ man interact with her or fall in love with her. And when you watch this video you can know how the man reaction with Sowon act. its such haaaa????? whats???? waaa???? hah???? its very funny.... like that. they are startled/ shoked. hahahaha the sagitarius artist are always like that. for example Yuri, Nayoung Pristin, chanyeol, minho shinee, and kang daniel.
