Honey no, since her brother’s life, the fame, since April doesn’t even know about Kpop so she doesn’t know about CORTIS, which is a good thing for Martin, Kirby will actually think to himself and say things to himself in his head), 5 minutes later, Martin comes into the kitchen to grab a drink and he notices April trying to act intimating by glaring at him but he’ll just look at her and then he’ll walk back out of the kitchen, and that’s makes April freeze that Martin didn’t get intimidated and that gets her frustrated and also very very very annoyed, and Kirby noticed that attempt and he’ll just chuckle since nice try April, while he’s still cooking and April is just simmering in anger since this isn’t going how it’s supposed too, which it’s supposed to go her way!! But Kirby will deny that and April will say things and Kirby will say things as April argues but Kirby won’t have it, and April is even more frustrated now, as Kirby is still cooking and April is still making the salad, and April will be saying things since damnit!! And Kirby will say things back while their still making dinner since Kirby’s now draining the pasta and making the sauce and April is putting the salad together still, and Kirby will guess April’s next plan since he knows she’s fixing to try something which frustrated April and she’ll say things and Kirby will say things, and Kirby will say things to April while April is simmering in frustration as Kirby is finishing up the pasta
