A Bit of Mountains and Rivers

“Keep it in your mouth... Swallow it... Baby, be good...“ 
“No... it’s very bitter...”
He feeds the sickly young girl with some medicine, as gently as he can. Unfortunately, she pouts and refuses to give in.

After being reborn as a 17-year-old, Luo Zheng seeks for Mr. CEO to repay his kindness. However, being too careless... she ends up being duped into marrying him, thus becoming Mrs. Bo! 
'What happened to the sham marriage that we agreed on?'
“Be good, let me kiss you, just once.”
“Be good, you must listen to me. I’ll pamper you.”
“Be good, stay away from him. I don’t like it.”
......
Finally, she loses her temper and pushes him away while protesting, “Bo Hancheng, you jerk. I don’t want to repay you for your kindness anymore, I want a divorce!” 
“Be good and stop throwing a tantrum. Divorce doesn’t exist in my dictionary, only... a deceased spouse does.”
Resolute and ruthless, his hands are stained with blood; he’s cold and unfeeling... 
He carefully retracts his talon-like hands and gently pulls her back to him. He decides to shower her with all his love and he swears to pamper his wife to bits!

Bo Hancheng had always been strict with the things he wanted and it would be best if they were perfect.

The same would apply to Luo Zheng too!

He began to regain his bodily warmth and he lowered his head to kiss her on her forehead. "What a clean girl. You must know how to protect yourself and you must shy away from tasting the forbidden fruit."

Upon hearing his praises, she suddenly began to blush and her heart raced. "If… Brother Cheng wants it… I can… "

"It's just three months, isn't it? I can afford to wait!" Bo Hancheng gently interjected while still staying firm.

"You're still underage so you must protect yourself. Got it? You can't give yourself to anyone including me!" He seemed to be lecturing her like an elder.

At the thought of Luo Zheng's reply just now, he added, "Throw those nonsensical books away. Don't read them again! If you're really curious, there'll be chances for me to teach you in the future."
