I guess there's like a slight resemblance in those pics but really they don't that much alike. I agree. Both give off sorta the same vib. Both are cute, prettiful, and mature.
I actually didn't know Hara was older than Mandu. SoHee looks older. ; I like Mandu like a tiny tad better but that's because I've been a WonderFul longer (sorry and no offense)
But yes both are like the adorable maknaes of the group...even though technically Hara isn't really the maknae. She looks like it though....well to me she does XD
