I just saw Jung Eun-ji and Seo In-guk's M Countdown duet performance lol

You sang Sechskies' "Couple" on M Countdown.

I really enjoyed watching Reply 1997, which the two of you were in.

It’s been over 10 years since then, but why am I the only one who has aged?

Both of you are still stunningly beautiful.

Anyway, Cross with a pleasant voice

It was a wonderful duet.
