you two are strangers, you are standing on the train because you can't get a seat while playing with your phone, you are a billionaire who lives a simple life, you are going out of town because of your daddy's work, and your car is broken so you take the train, you want to take the first class train but all the tickets are full so you are forced to get on the regular train

suddenly you feel a little pushed by someone behind, and it is Chau Yuet who just got on the train

oh! were you pushed? sorry, just now there was just a little space so I could get in

Chau yuet bows a little then fixes his hair
