Eren tapped his fingers on the round table as he pondered.
He had already decided what he wanted from her. But he didn't think he would be offered three rewards. So it took him some time to answer Osha's question.
Eren decided to reserve his first reward for later use.
He requested Osha's visit to the city of White Raven as his second reward. He told her he would contact her when she was needed in his city. The latter was only supposed to come to his city and stay for a few days before leaving.
For his third reward, Eren asked Osha to dance with him for a few minutes when the Ball started. He didn't put much thought into his third reward and just asked for a dance randomly.
Osha agreed to all his demands easily. She smiled and raised a toast to him. She chugged the contents of her glass in one gulp. She drank two more times to signal her defeat before speaking further.
"I must say I underestimated you, Grimdawn. We all did. Congratulations and well played."
