So I was on the bus on my way back home from work.

There's this chick sitting across me (facing me). I was looking for some iois but all she ever gave me was a quick glance. I live in an Asian country so girls don't come off too aggressive.

She had earphones in.

Is this a situation where my smv just wasn't high enough for her? Should I have done something to grab her attention?

She was a bit too far to strike a convo and she didn't get off at the same stop as I did.
