Pledis' Heo Yoonjin
-It doesn't matter since she looks beautiful..ㅋㅋㅋ
-I think rather than looking older than she actually is, she just looks a little bit more matured than girls her age..
-She looks like the combination of Jiyeon and Kim Jiwon..
-I thought she was born in 1997-ish.. She's so young..
-Well, I thought Jurina was 32 years old..
-Whoa, but I think she would still look exactly like this in the next 10 years..
-I think it's just because of her hair and make up.. She looks like 18 years old..
-I don't think she looks older than her age. She's beautiful.
-She indeed looks more matured than girls her age, but she somehow looks very cute and pretty as well!
-When she called Lee Gaeun 'Unnie', I assumed she was born in 1996 or 1997..
-But Yoonjin is beautiful!
-She looks like Chanyeol's older sister..
