D-Nation Entertainment announced Park Bom's Fan-Event called "Snack Event" to celebrate 4:44's promo run but also the fans, whom showed lots of love towards Bom. Fans will be able to get free drinks and food, and the ones who have several stamps within the timeline of the 4:44 promo run, can get signed 'merch' for free. 

While D-Nation didn't necessarily reveal that Bom will be present during the fan event, it is highly likely so, as they also shared that the Snack Event's date, which is June the 30th, might get re-scheduled if Bom has a sudden important different schedule. Though it's not likely, the possibility has already been announced. That makes fans believe that Bom might be there as well.
