Erin is the girl who think sad is not her style. She's always happy. But it doesn't mean that she's never been sad. She's the kind of girl that will smile when she's sad and laugh when she's hurt. But, she can be really sad if she doesn't get to eat yogurt or french fries whenever she wants them. Your first imperession of her is cheerful and friendly. She think crying makes you weak. Her happy go lucky type of personality is fun to be around. She knows what she's doing and knows how to have fun. Her pat friends called her the mood maker and peace maker. She can't always be happy but she tries to be any ways. It always too hard for her to trust her friend because of her park past. She doesn't want to be betrayed by her friends anymore.

Altough she seems cheerful and bubbly, she's actually a troublemaker, sarcastic, stubborn and quite boy-ish. She doesn't care if people annoys her but, if it's really really annoying, she'll say it immediately and won't even hesitate to fight if it's necessary. However, she doesn't like to be angry and hold grudges so she forgive easily. But, if she hold grudge at you, be prepared. She will play pranks -mostly something related to scary thing- on you.  She is also good at making smart remarks. She tends to call everyone by their position or 'Oi' for example she will call the maknae 'Maknae' or she would simply call out their full name like 'Yah ________!'. She has an obsession with music therefore always has her headphones with her except for on occasions where she’s not allowed to bring them. She isn't one to freely express her emotions, so every time she feels upset, she goes to the Han River -- regardless of how far she is away from it, and she'll confront the river about all her problems. She views the river as her best friend who will never leaves her side. She likes to confrot people but she really hates people confrot her

 When Erin glares and smirks or has a pissed off look, you better run for your life. Her glares and looks are trade marks for when she is really pissed off and someone has just made her blood boil to the max making her go crazy and start throwing things or hit the person who just pissed her off.  She really cares for the people she loves, you wouldn't want to mess with her or her loved ones cause she might chop your neck off so get on her bad side, and you've got a total killer trailing behind your every movement.
