You're on your way to your friend's house. Her name is Yui. The train is full but luckily you have a bit space... Until the train shakes and you stumble forward into a lady's chest.

you look up at her and she has a rather pretty normal expression on her face. "I'm not hurting you, am I?" she has a soft tone in her voice "Are you all alone here? Where are you headed?" she doesn't seem too bothered about you having your head basically buried in her chest
