Qiao Qing answered, "It's the birthday gift I bought for my brother."
Jun Yexuan's tone was sour, "What is it?"
Qiao Qing, "A wristwatch."
Jun Yexuan, "He doesn't lack those."
Qiao Qing, "… You don't lack belts."
Jun Yexuan, "Then, can you buy me something I lack right now?"
Qiao Qing, "What?"
"Security." Jun Yexuan answered, "Qingqing, I've never really been afraid of anything all my life. But now, I'm just scared to lose you. I don't feel as cool as I make it seem. I worry that once you reveal your identity, the Qi family won't accept me."
Qiao Qing paused, "How do I provide you with security?"
Jun Yexuan pulled her into his arms, "We can have a baby or get a marriage license. What do you prefer?"
Qiao Qing, "…"
In the end, Jun Yexuan failed to trick Qiao Qing.
After they returned home, Qiao Qing continued to split her time between the library and the laboratory.
