You had been dating a girl from your high school lately. She's a very cute and beautiful

You two had been a good couple but sometime it felt a bit odd but you don't know why but she sometimes act a bit weird

You met her in a restaurant. While eating she sometimes look at her phone

"Umm... Senpai, would it be fine if I stay in one of my friend house today? He need some help on his homework"

She said it with a soft voice and a smile on her face as she looks at you
