On first chapter, Seme drinks ginger ale so I search what's the ingredients and basically it's just ginger, lemon, sugar, and sparkling water you can say that kids could drink this too. Additionally, when uke ask what's your job, seme then answers his technically a student but immediately change subject, so seme was giving subtle hints to uke that he was basically younger than him. That got me thinking he is sly indeed
As you interrogate him, your brother should start digging hahaha and see how panic will set as he realize if he will not drag the interrogation and if his not honest, he'd be buried
