Alright, he's trying to be a better person. It's getting a little harder for me to dislike MC. (Only a little, though. He still jerked off to her getting assaulted.)
But Ayana is completely out of fucking pocket. She even bugged his phone now??? The chick is insane and you know it's only going to get worse from here...
Oh no, for me it's the opposite. I still feel disdain towards the MC, if anything it's growing disdain.
Keep in mind, he actively ignored her and abandoned her. She is showing that she is afraid of returning home, indicating that either there is mental trauma or the gramps is still living there and raping her on the daily.
His father is a cop, but he did and said nothing to resolve this issue.
She is being bullied at school apparently, and he only now found out, meaning he is actively avoiding her at school too, so not only is he complicit in letting her suffer in her private life, but also potentially in her public life. Mind you this is more of a case of general ignorance at school, after all you can't tell what happens to someone else 24/7. But I find it highly unlikely that he didn't at least hear some amount of bullying before this.
And his inner monologue seems to suggest he thinks of himself as the ultimate victim in all of this, he wants to move on, be happy, thinks of her as his happy childhood friend initially and only after being confronted with the result of his cowardly actions haunting him does he start to show any amount of regret and wanting to undo the damage he's done. But even now he's still doing it in half measures.
And we also know that he still lusts for his childhood friend too during his Shinji jerking off session, he had his wires crossed for a moment and kept jerking it off with two separate fantasies.
He's a bum, a coward, a scumbag, a cuck and a hypocrite.
Now, mind you. She's a menhera yandere and a coward too. She absolutely should be going to the police to report her grampa, though that's also us asking a little teenager to surmount her trauma which is far more difficult than asking a teenage boy to let his testosterone go wild and get him on an adrenaline rush to save his friend.
Because this is important to remember. Despite the size of her badonkadonkers. These are kids. These are high schoolers. I expect high schoolers to do stupid things. But I also expect that when confronted with a horrific situation that is far out of the norm, that the true nature of a person will come forward. And in the case of our MC, while young, showed us exactly who he is.
