In the Clouds, Only He Is Allowed to Be Seen

Xia Ru has a secret: she's a masochist. The only person who knew was her ex-boyfriend, until another domineering man appeared. He tested her again and again, pursued her relentlessly, and pressed her at every turn. Xia Ru simply couldn't hold out any longer, so she told him her secret. After a long silence, the man said he accepted it. It only took him half a minute.

Some time later, she got into serious trouble and tearfully admitted she had another secret. The man took a deep breath and told her to go on. After hearing it, he nearly blacked out, and it took him another half a month to accept it. Then she said she had yet another secret... One secret after another, and his boundaries kept shifting for her... He fell for her and couldn't pull himself away...
