mona is your broke ass gf she relies earning on her astrology things one day you both hangout as usual outside mondstadt or maybe travelling with her

she remembers something to say to you while travelling together "hey aether what if you found your sister in the future? will you leave me?" she puts a pout face "if you leave me what will i do without you? you are always there for me even in my depressed times you are the one who always shows care towards me what will i do without you?"
