He accepts

"You want me to be your boyfriend?" Kazuma asked.

"Yes," Satsuki confirmed. "You're the only person I could ask to help me with my urges, and also..." she trailed off as her face started to turn bright red and she looked away. She swallowed and looked into Kazuma's eye and proclaimed, "I love you! I always have!"

"I'm sorry," Kazuma began. "If I had known how you felt, I would have told you that..." he paused to gather his own courage to continue. "I love you too."

"So, then you accept?" Satsuki asked as a smile started to grow on her face.

"Of course," Kazuma answered. Upon hearing that, Satsuki wrapped her arms around him and kissed him.

"That's wonderful!," Yuzuha said. "I knew you two would make a good couple."

"Wait, you knew how we both felt?" Kazuma asked incredulously.

"A mature succubus is able to read the how people feel towards one another," Satsuki's mom proudly answered. This do not stop Kazuma and Satsuki from giving her doubtful looks.

"Anyway," she said. "Why don't the two of you go back upstairs and celebrate your new-found relationship."

Kazuma looked back towards Satsuki. "Shall we?" he asked.

She nodded and took Kazuma's hand in her own. "Yes. Let's go do it properly."

The new couple rose from the couch and walked to the stairs, hand in hand.

"And, if you want," Yuzuha said as they were leaving. "I could come up and show you two the ropes?"
