You were in relationship with Runa for 2 weeks now and your already both comfortable with each other that you both share the same room

One day in Tokyo, you both rented a condo a day ago where the full city can be viewed, you go to your room and sees Runa sitting on the bed wearing baggy shirt and only wearing black panties, she got startled

Runa: "Oh! H-.. hey babe~.. didn't notice you there, hehe" she chuckles nervously
