"You fell in love with him, didn't you?" Kaede suddenly asked.
Setsuka's face didn't change when she heard that like she had expected Kaede would ask about it. Kaede was her best friend, and they had known each other for a long time, so it was natural that she would know how Setsuka felt. After she got a lot of proof about that, she could more confidently ask Setsuka that question.
"Yes, you're right. I love him." Setsuka admitted it. She had no intention of hiding it from her best friend. Sooner or later, Kaede would find out about that.
