[Special Clip] Lee Si Eun 'Sometimes' 

I dont know, but all artists in HFE deserves some more attention .

Happyface single handedly bringing back rock ballads to showcase their artist's soft and powerful vocals.

HFE GOT SO MANY GEMS IN THEIR COMPANY HUH?! I like her voice 😭❤️

I started to be HF stan. HF have amazing talented artist, idols and trainee. May HF will be shine more as other company in SK.

I feel bad for not knowing her, I should check Dreamcatcher's label mates since there is real talent there. Such a beautiful voice and she knows how to make us feel the emotion in it

HFE collecting great vocalists, wbk

HFE got many underrated artists

Quality is more important than quantity - HFE motto

HFE is full of talents..

We need a Happyface family special song! With Dreamcatcher, D1CE, Lee Sieun, Oh Seohyun, other trainees and artists. As an Insomnia I feel like I've only known Dal Shabet, D1CE and Dreamcatcher to this point, but I am missing out on so many great artists! Please show us them more Happyface!! If Sm can make a family we can make a Happyface family
