Miya is the annoying and that dude is sus af

"Something important for who, I wonder"... I just had this urge to tell that guy to f*ck himself out of their issues, really (╬￣皿￣)凸

I reread the entire manga after reading your comment and I tried my best to look out for Miya's friend gaslighting her, but I don't really see it. Miya needed some time away from her father and he kept her company, he didn't try to force her to stay away from home, he didn't say "come to my house to hide away" he visited her when she rented out a hotel room for a few days, and whenever she talks about how she's feeling about something he continues the conversation and asks questions. He also thinks that Kousuke is dating Koto after what he saw so he's also using his own judgement like any normal person would. He's also the only person that Miya can really talk to about things like this since he was there to see shit go down.

But is Miya talking things out with him?

No, she's just doing the same as with her mother, shutting herself in to avoid the talk she and her father need.

The difference being that now she's doing it at some random guy's house. Showing her weak side to a complete stranger that for all we know is waiting his chance for her to open up and take advantage of her.

He's just telling her what she wants to hear so she can feel safe with him as he bides his time to make his move. He admits is interested in her, but doesn't do sh*t to help her deal with the issue with his father. Father, that if anyone remember was and is committed to his duty at home.

Okay, it seems that you're more focused on "what could happen" rather than was is happening right now. She never went to her friend's house, she went to a hotel when she wanted some time away from Kousuke. Now that that's cleared up, it's understandable that she doesn't want that talk with her Dad. Imagine being in her shoes; having the same suspicions as her, having her childhood friend tell her that she's interested in her Dad, then getting a text from her Dad saying that they need to have an important conversation? Having someone who listen to you without judgement is a good thing, too. Miya's friend (who goes to her school and who she also hangs out with. He's a stranger to YOU, NOT HER. It's obvious that they've bonded off screen.) seems like one of those friends who listens more than they speak, which seems like he doesn't mind and is also something that Miya needs right now. The only thing he said that seemed a little bit predatory (but I had to look real close) was when he asked Miya how amazing it felt to be free from her Dad, but that just seems like regular teenager talk. I think he said that he was interested in her because they just bonded over time. Which is understandable.

It seems like Kousuke just wants Miya to have a good life, like every parent should wish for their child, but he keeps having a relationship with Koto, which he knows hurts Miya. Imagine how creepy it'd feel if your own father started dating somebody your own age, especially your classmate and childhood friend. I feel like a lot of people here aren't looking at things from Miya's perspective and they're putting Miya and her friend in a bad light simply for finding it disturbing that a 15-16 year old is interested in a 40 year old, which is normal to find disturbing.

My bad, I throw one too many assumptions. Still, her father never let her down at home, not showed any signs of he being some kind of deviant. He's a good father and she's just brushing that off because she blames what happened to her mom on him.

I still doubt the intentions of the dude. If he really were looking out for her, he would bring her to her dad so they can talk, not alone of course, he would be there with her to help her and give her support. He just doesn't care and still throw opinions on her father's intentions based on nothing to stir Miya's head even more.

Exactly what i've been thinking. Thank you for saying it.
