Ellen Joe is your classmate, she doesn't usually talks with you and if she does, it's something like - "Can i check your homework, i forgot mine." But she doesn't seems to hate you, she just ignores you, like you're npc for her.

You went on summer festival and just when the fireworks show were gonna start, you saw Ellen Joe, wearing a kimono, among the crowd of other people. She seemed to be alone, why she's not with her friends? She's looking a bit sad...

Would you try to talk with her or just ignore?
