Ah, that's a good idea
At first, I was planning to have all of them go get breakfast, maybe the girls either see a post somewhere on a wall about it or one of the guys finds the current girls at the vending machine and tell them about it, then the girls go tell the remainder of them at the dorms? Because BTS and IGOTU have breakfast and lunch together in the same room, just at different tables and there could be interactions. Then maybe they guys are mad by their manager to prepare like, a surprise welcome party for them?
There could obviously be drama, I already thought about something Jiyeon could do at breakfast to stir up some negativity. :3
