In my opinion, most of the situations you are talking about is an ancient ritual where girls in a mixed group with one guy ganging up against him and start teasing him constantly. And his girlfriend has the main role in this show, when she loudly and theatrically complains to her friends about how bad he is, how little he cares about her, fucks her only three times a day and only tells her fifty times a week how much he loves her. If they didn’t tease him, it would mean only one thing, they are not interested in him at all, and if his girlfriend is among them, he seems to have problems in relationship.
In the meantime, Miru acts in the MC's best interests. She spies on his relatives and collects information for him. He has no idea how to behave with them now, after a long break. She helps him with that. And the situation with Helen is driving him crazy, he doesn’t understand what the hell is going on here.
In Katie's situation, I see Miru as a driving instructor who, perhaps somewhat rudely, points out the MC's mistakes in real time and demands that they be corrected. Wouldn't you agree that the ultimate goal of her actions is to help MC find common ground with the grown-up Katie and get rid of the old quarells?
In the scene with Gina, Miru gets angry at him when he greets Gina in a rude manner. It is clear that the MC and Gina have such a close relationship that a joke about her weight is not perceived by her as something offensive, but nevertheless, this is still asshole behavior on his part and Miru immediately lets the MC know about it.
Well he should work on his moves then and impress her.
Whether he is bored or not is up to you, the player, to decide.
Nah, I don’t see any bdsm-ish tendencies in her behavior, she doesn’t behave like a typical mistress in a leather outfit. I'd say she's very gentle and submissive with him (although she almost always initiates intercourse) and they've been pretty vanilla so far in private.
It's hard to argue with that. But you don't mean that Miru is keeping him around by brute force, right?
But he can have cowardly (in the sense of fear of the consequences of his actions) and selfish motivation, but at the same time act with determination, showing a strong will in achieving his selfish goals. I don't see any real contradiction here.
I think the fact that he ran away from home instead of trying to resolve the conflict just shows that he was a typical teenager who had no life experience and acted impulsively without thinking.
If he had put his will and determination into finding a better solution, I'm sure he wouldn't have had to run away and we wouldn't have WiAB, because there would be nothing to tell about
What the hell, half the plots of literature are based on stupid decisions and their consequences.
And at least I don't think he was acting selfishly. Stupid, yes, but he believed that he was protecting his loved ones and saving his family from breaking.
