Ruka was totally savage, I liked how she told off Mami, but I think that should have done by the mc. That bastard needs some character development, he is too annoying.
I want to see Mami more in the future, Im curious about her circumstances, why she decided to go out with the mc, why she broke up, why se keeps stalking him...
It feels like she is slowly turning into a yandere, I hope after seeing that bag everything turns into a bloodbath.
