I love this story and I've been waiting for this chapter but...im sorry to if im gonna sound horrible...after his fancy confident talk about tea did he just boil water and poured it on a tea bag? He's trying to be all fancy and stuff with how he talks i thought he'd atleast use loose leaf tea: higher quality, whole leaves, more flavorful. Tea bags: lower quality, dust and broken leaves. Also Klee is a child why not put some milk in it. There's a lot of stuff online you can use to write the whole fancy shop theme from making coffee, tea, baking breads and making desserts. Again sorry.
