Taeyeon released a new set of teaser content to bring further sneak peek into the concept of her 5th mini-album 'To. X.'

On November 17 at midnight KST, the Girls' Generation member released a teaser clip and photo. In the short clip, Taeyeon receives a series of text messages from 'X' and goes through the process of breaking up.

In the messages, 'X' says, "Because it's me, I'm seeing you," "I'm saying this because I love you," "Stop it, I don't want to hear it anymore," "I told you that I don't like you doing this," "Don't just think the way you want, listen to me," "I didn't mean to say it in that way. Why are you like this?" "You always think the way you want," "There's no end if you keep thinking negatively," and "Why are you so edgy these days?" 

In the last message, 'X' sends, "Let's meet and talk. I'm busy these days so let's briefly meet on the 27th."

Meanwhile, 'To. X' will be released on November 27 KST.
