Subconsciously

 And as long as that happened, the boy had been holding her.

After that …

 Ah, Vio felt unable to remember it anymore. Her hands moved quickly to grab the pillow to cover her hot face.

 This is embarrassing!

 She felt like crying. Vio felt unable to meet face to face with the boy if she later met him.

 Coming to that thought, Vio removed the pillow from her face. Inhale as much air as possible with her lungs.

 Calm down Vio! Calm! Think of something!

 Ting!

 A light bulb appeared in her head.

 She had to run! Yes that is right! She will run away from here!

With that determination, Vio walked towards the door. However, when she was about to turn the doorknob, her movement was stopped. She might actually run into that boy out there.

 With that in mind, Vio turned towards the balcony. Opened the door slowly, then stepped out. There is no one.
