I'm really interested in her, but I don't know how to approach a girl on a train.
If you're in Japan, the correct answer is "grab without consent" apparently.
look at her with breaks but not stare always. make her notice your intrest then go and talk to her about her studies where she lives start the conversation with hey
just go stand or sit next to her don't ask and start talking to her if u guys get along ask her out one day or that day
