[All] Haein also sang the OST in Mom's Friend's Son

Haein, you really have the skills to be believed even if you were a professional singer.

You sing so well

Since it is a drama music video, there are many cute moments of the couple Seunghyo and Seokryu throughout the video.

I'm falling for it again

I keep thinking about it when I watch a drama after a long time haha
