should have choked a bitch there would have been better

Agree with the sentiment but MC is loyal to the grandpa and wouldn't do anything while thinking it would shame him while MC thought grandpa was still there. As long as the Auntie is unable to tattle he will likely do whatever he wants now though judging from how much he seems to dislike the 2 ladies by end of 3rd chapter. MC listens to grandpa and the girl and her mother disrespected he who is worshipped.
