Koi ga Shitai x3 episode 1
[contains only information about Miyanishi Noa]
At around the 40 minute mark (in the TV broadcast), there is a scene in the bedroom of Shimura Ichirou (played by Oikawa Mitsuhiro). A young girl is sleeping in the bed next to Ichirou. This is a very dark scene, with only the moonlight lighting the room.
The scene is less than 30 seconds, and if you don't look very closely, you won't see who the girl is. This girl was played by Miyanishi Noa. She was sleeping the whole time, so she never opened her eyes. Obviously, there were no spoken lines by Noa.
