He probably likes it himself? I mean he styles it well and if you ask me he looks good in anything. If you really like him then a simple hairstyle shouldnt be a big concern for you
Honestly, your comment is a shame, it's his hair, if he wants to shave it, let him shave it, it's his hair, I repeat, HIS HAIR. If he likes it, all is well. You don't have to like it, or me, or anyone else, Jinnie doesn't belong to us, and what she does with her body is none of our business. Because of people like you there are idols who are afraid to be themselves.
