Erwin arrived in front of Sabrina's door but he didn't know what he should say. He was still hesitating and was doubting himself but he also wanted to know what he did to upset her. He was torn between these two things and was pacing back and forth in front of her door.
Sabrina, on the other hand, was busy looking for clothes. She planned to go out after lunch and she will drag Erwin along to annoy him again. She had no idea that the man was right in front of her room.
