Jimin said long hair not that important, but he like girl with long hair since young, and Jeongyeon started grow her hair during signal era (2017), right? at that moment she already wear her couple rings with Jimin (chrome hearts rings), i think she started growing her hair like her pre debut days again because Jimin like long hair, and they started have many same clothes in this year too, and you can't says it just ordinary coincidence, because there is a picture of their yellow couple shirts on the poster muster official BTS, i already shared that evidence
Chaeyoung said Jeongyeon is really pretty during trainee days when she had long hair, for her Jeongyeon is the prettiest among trainees at that time
even they cut her hair short at the start of TWICE debut, she still pretty, girls who can rocks short hairstyles are very pretty to me, because not many girls can rocks it
even though Jeongyeon's hair was that short she was still beautiful thats why many korean male celebrities said likes her on TV, but after 2016 no more male celeb who mention her name again, even though her hair is getting longer and she is getting more beautiful everyday
do you know what i mean, maybe because of him 😁😁😁😁😁
