"Well, it was because she was sleepy earlier. That was why she was in the guest room." Xiao Tian lied to Crystal.
"Then why were you in the guest room with her?" she threw another question at him.
Instead of answering her question immediately, he asked, "Crystal, do you really not know?"
"Yes." She gave an honest answer. "That's why I'm curious about it."
He looked at her before returning his attention to the road. "Do you really want to know the truth?"
"Yes." She nodded her head.
"I had sex with her in the guest room earlier." He gave an honest answer. "She walked strangely because we had wild sex for long time."
She widened her eyes in surprise. "Sex?"
"Yes." He still acted calm despite telling the truth.
"Is she your lover now?" she asked curiously.
"No. We are only business partners." he responded, "It can be said our relationship is only friends with benefits."
