Haerin has a straightforward personality; definitely not one to sugarcoat and also sees lying unreasonable. She is also quite a bold character because of how at times she's so willing to do everything, anything. Haerin is someone that has everything you call outgoing, a little ball of sunshine literally. As a prankster who loves mischief, she would often play pranks to everyone but her aegyo, which is something people can't resist, have always given her a gateway out of trouble. Creativity flows through her very veins; since she loves something new and she likes to go to places she hasn't been to before. Haerin feels pressure whenever and would overwork herself when she doesn't meet her own standard and she is above all competitive.

She gives great importance to what other people would say and she is also someone who can't possibly keep shut. Losing isn't a part of her volcabulary. Mostly known for being easy-going, you'd think Haerin would be someone who wouldn't work her off but it's the complete opposite and even though she has a lot of free time to do petty things such as taking walks and baking, it's just because she knows how to handle her schedule as an idol and her me-time off stage.

She is also said to be good with words and she has excellent persuading skills.

She laughs and smiles whole-heartedly; she isn't one to fake and if ever she's uncomfortable and staight-on awkward, you'd often see it because of her body language and the way she cringes. She also cries easily, like how she would cry during sad parts in movies and dramas. Haerin is sincere, kind, sweet, and knows how to take care of other people. Many people has also said Haerin, surprisingly, has a split personality; her mature side and her childish side. She is quite childish and often would whine about small things and thrown jokes every now and then but when she knows it's a serious matter, she would turn serious and even though she says otherwise, she is a good listener and someone who'd give good advices.

Haerin is a keeper and is a fool for a good romance; she always longs for a long-lasting, commiting, all in kind relationship. She has a soft yet sacrificing nature; this is good in a sense that if she must give up on a good opportunity for her loved ones then she would but in that way, she also sometimes would think that her loved ones is playing her.
