Hanako was with her brother like a ticks, as normal, when her brother (Taro) said that he needed to go to the bathroom, so she stayed in her place

She was looking around looking for something that she can distract herself with, when she saw you and thought ("Wow, i think big bro can already take care of himself alone, I need to talk to them!") And then, she walked towards you "Hi there!, what's your name?" she asked with a smile
