@Floriano You are just a bonobo and don't understand that these moments are meant for gag,
As well as Erika being a spoiled brat, which will be fixed over time, Erika is giving Nagi support and Nagi her, it's been progressing exactly like this since the beginning.
In a situation where no one would talk to him, she came up and gave him a tantrum that just because he failed once doesn't mean he became garbage (he called himself garbage).
None of her actions were malicious, she just doesn't see a reason to sulk like this and as we can see it worked out and Nagi is back at it, because their convo moved him further, they pretty much hold a interdependent relationship, and we'll see more of that going further.
I'll enjoy the weekly salt reads here and on reddit tho, i hope we'll all still see each other at the last chapter the dunks.
