Just imagine Banri playing Genshin in the living room and Kazu sits besides him "Setzer whatcha doin" and Banri replies with "Hm, just ascended so im tryna defeat this bitch" Kazu looks at his phone and goes "Hm, okay" 7 mins later Banri, confused at the lack of Kazu's usual

chatter, glances at him and sees him sketching something on his ipad. A few seconds later Banri goes "wait a sec" and does a double take because holy fucking that's a sketch of his Ganyu aiming at a leaping frog oceanid, eerily similar to the scene of his battle earlier, and

Banri slowly lifts his eyes to stare at Kazunari's relaxed face, as if sketching Ganyu and that leaping frog is just a simple past time to him, and taught to himself "yeah... i need to learn that."
