Jackson Wang isn't letting go of the year just yet. 

In a post made via Twitter, the GOT7 member teased his upcoming single '過 Should’ve Let Go' with a 20-second teaser. The video sees Jackson in a bus during a raining night, reminiscing of a past relationship before singing the lyrics "should have let go".

The track with its accompanying music video is slated for release on 17 December.
