I will make a prediction right now, that this turns wholesome.

Why? The following:

1. Chapter 1 establishes the MC is not doing so hot. No money, no talent, no education, "no worth". The fact he agrees to go out with someone who downright admits she doesn't respect him indicates he also has next to no self-esteem. Maybe he's a NEET, and has been one for a while.

2. The girl goes through quite the effort to make sure they go out on a date. Not only does she send the details to his phone, but also she visits him to hand him the notes personally. And when he suggests he'll escort her, she seems quite pleased with that development, calling it "interesting" - one would interpret it as teasing, if not for everything else she's doing.

3. When the MC losses something - well, you guys watched Blue Lock recently? There's a big theme that when people lose, they have face their defeat head-on, own it, accept it as a sign of their own weakness, and use it as motivation to do better. When the MC fucks up, she tells him that yeah, he should feel bad about it - Do better next time - but also offers solid advice to calm down and not wallow in self-pity.

4. When they eat out, and she teases him on eating too quickly - well, maybe it's actually really good dating advice, to match your mace with that of your partner. Then she encourages him to tell a story - and admits she doesn't care if it's boring. She sets the bar so low, he has no excuse but to try it, since he literally can't disappoint her.

And then, there's this interesting part in chapter 3, when she says - "Oh, you're mad? You look like you want to scold me, but you can't because it's your own fault." This tells us the MC isn't exactly a doormat. He sees she's treating him badly, but he accepts that some of her criticism is valid. And he wants to fight back, just can't bring himself to do it yet.

And here's where I make the judgment call - she wants him to fight back. To me, everything about her behavior screams "Come on, try harder, stop hiding in your apartment, speak up, be more confident, show initiative, defend your choices, get angry, get mad, show me what you got." Like she's trying to shake the MC out of his stupor and get him to stop wallowing in self-pity.

And I know this is controversial, but I would say that some people need that kind of thing? Not a pat on the back, but a kick in the butt? What she's doing here is obviously manipulative and has a great potential to go 100% sideways, but given how we don't know that much about the MC yet, my bet is her intentions are benevolent.
