Oh My Girl's Arin live singing today was so severe

I think she needs to practice a little bit more..ㅠㅠ

-She's exploding with extra-cuteness..

-I mean.. Why does she look like she's gonna cry through out the whole stage;; That surprised me..

-Her expression.. She looks like she's gonna cryㅠㅠ

-The more important thing here is not her live singing.. Why does she look so sad during this stage?

-First of all, look at her facial expressions.. And also, what's up with the song and choreography..

-Judging by how her face darkens whenever her part comes up, seems like she's feeling uneasy or anxious to sing this song.. But is that her original voice? Or is she using her head voice?

-The key for this song is seriously so high.. They should've just lipsynced it if they find it hard to sing live..

-Her facial expressions look especially dark today.. What happened?

-Forget about the live singing.. She usually didn't have that facial expressions, seems like something bad happened to her..

-Oh..? She looks so sad today. I've watched some of the other videos of the same song and she had cheerful expressions on..

-She somehow looks sick today..

-Is Arin sick..?

-Her facial expression looks kinda bad today.. Is she sick?

-Why does she look like she's tearing up..?
