So Kaya's husband has returned home so this is probably good timing for her, to cheer her up and stop moping for a little while.
Her body hasn't changed much, maybe her hair is a little bit longer. She'll want to explore everything, especially the gardens and areas with flowers and plants. So please go with her and escort this clumsy sweetheart. Talking about inhibitions, she'll be much more prone to hug people and make physical contact, especially her roomies. She hasn't gone to the library or any textbook-oriented class while he's been here because she's self-conscious about her limited knowledge; while in Botani, she'll want to dare to check intellectual stuff out she previously thought she was too dumb for. Try reading a book, which intimidates her right now. Go to a museum/concert/play. Indulge in her curiosity more? Besides that, she'll check the restaurants and the fireworks.
