Junghwan, the youngest of the upcoming YG boy group, TREASURE13 is looking sunny and cheerful in a new set of photos in their "preview image moment" series called 'Begin'. 

The young vocalist smiles wide as he wears a comfy, white knit sweater paired with a bright yellow collared shirt underneath. 

Junghwan is part of TREASURE13's subunit, 'TREASURE', which was created on the music survival show, 'YG Treasure Box'. The other subunit that completes TREASURE13 is 'MAGNUM', which was also created through 'YG Treasure Box' and makes up six of the thirteen members of the group.

YG has been consistent in releasing teaser photos of all thirteen members of TREASURE13 for the past few weeks in anticipation of their debut later this year.
