Had two uncomfortable encounters in Hyderabad Metro today, is this normal?

I’m a student and was travelling from JNTU towards Victoria Memorial today to visit a friend.

Before Ameerpet station, a guy in his mid-20s sat next to me and started talking and flirting even though I wasn’t encouraging it. Just before getting down, he asked to exchange numbers. I felt awkward saying no, so I gave my Instagram instead.

Later, at Irrum Manzil, another man (early 30s) sat beside me and kept peeking into my phone while I was scrolling. I confronted him, but he still asked my name and whether I’m a student or working. Even after that, he kept trying to glance at my screen.

Both incidents made me really uncomfortable and uneasy.

Is this common while travelling in the metro, or am I overthinking?
