"Noe this is the best manga ever and I know because I am very intelligent and you can only envy my and Kazuya's superior Love Mastery. Stop regurigating all these cridisisms!"
Every time we get a Chizz internal monologue chapter, we see she's just as freaked out around him as he is around her. This time, we just get her awkwardness without the narrative and it's creepy. Creepier than Kaz without HIS internal monologue by far.
I imagine this as zero internal monologue.
Something he's so messed up by he wouldn't even show the reader his thoughts like he usually does.
And also it wouldn't be tonally effective to handle something like that as a writer. It wouldn't do to convey complexes and traumas in a style of a hyperactive chipmunk.
