Korean girl, HB4~7.8 depending on perspective (I realized that there's a huge variation in HB score in asian girls depending on the ethnicity of the beholder). The following takes place over a period of a week.

1st Point of Interest (PoI): I ran into her at the gym

Class: Hey, you're in xxx class right?

Yeah.

Class: I remember you because you asked a question about xxx

Haha, yeah. It's because xxx xxx xxx.

Class: What class are you taking?

small talk about classes, where we're from, etc.

Class: Alright, I need to get back to workout, I'll see you around!

2nd PoI: class She changed her seats multiple times, and I see she took the front seat next to where I usually sit. So I know there's some interest going on. I decide to talk to others and keep her starving for attention. For example, I get to know the guy behind me. When I talk to him, I'm turning my chest towards her so she's fully aware of my presence but my verbal and body language doesn't give any attention to her.

When it's finally a break, couple of us come up to the front including her, a friend, and me. At this point I finally acknowledge her. (1). After a bit of talk I again ignore her and turn to my friend. After class, I head back with the same friend. I know she walks nearby for a bit of distance, but ignore her.

3rd PoI: gym

I'm glad to have run into her because my partner and I've just opened up 2 different groups totaling 5 guys...except I ran into her isolated from the group so I couldn't get social proof (such a letdown). We talk about our majors, our post-graduate plans, etc. I realize that she has some insecurity issues about doing well in class, getting into a graduate school, her gpa, etc. (2). I do a very light level of kino (touch on arm) to tell her to relax and suggest that we study together sometime. By this time, my eye contact has been very steady but I've been moving away from her, not because I wanted to show time constraint but because I really had to get back to finish workout and go to a dinner plan. (3).

At this point, I know she's interested from her body language and behavior. I also know she has some insecurities. My goal is to seduce her mentally, not necessarily physically. What are some paths to take when a girl shows insecurities? What are some things other than small talk I can do before/in/after class and during a break to raise interest? What is a way to manifest time restraint without making the impression of cutting the person off (a nice and fluid way to say I need to get going)? Should I keep alternating between starving her for attention and acknowledging her in a limited magnitude? Or start to initiate (number, study together, dinner, etc.)? I should add we're entering 3rd week of a 10 week class

(1) What I didn't do but should've done was to introduce my friend to her so they could carry a conversation so that I would receive social proof while saving the socialization and talks for later in a more isolated setting.

(2) I don't know how to really take advantage of this sort of insecurity (or insecurity in general)

(3) I'm really bad with verbally making clear time restraint. I know I need to say something like "I need to get going in 2 minutes" but during a conversation I just sort of get into the habit of keeping it alive, keeping them interested, etc. I need to improve this.
