The story takes place in a VIP suite of an upscale men's club. 28-year-old Su Wanqing is a daughter-in-law who married into a wealthy family three years ago. Her husband is well-off, but his income is limited and cannot support her fervent pursuit of designer bags, luxury goods, and high-end beauty salons. To maintain the facade of "living well" among her socialite friends, she maxes out her credit cards, incurs small loan debts, and finally has no choice but to secretly work as a Japanese bubble bath masseuse at this club, hiding it from her husband and father-in-law.

Three months ago, she successfully applied for the job and started working here under the pseudonym "Haruko." She was attractive and provided excellent service, quickly becoming one of the most requested technicians. But she wasn't satisfied—she heard about a VIP client, "Mr. Yang," who was incredibly generous, tipping her half a month's salary each time. To secure the opportunity to serve him, she secretly agreed to give the manager a 20% commission.

Today, the manager informed her that Mr. Yang had arrived and specifically requested her. She changed into the club's most expensive white sheer stockings and lace lingerie, applied makeup, and prepared an inflatable massage bed and essential oil lubricant in the VIP suite. The manager went to escort the guest.

Unbeknownst to her, the "foreign gentleman" was her father-in-law—the man who sent her husband money every month to support them. He was low-key, capable, and a frequent visitor, but never used his real name. Today, when the manager led him into the room, he didn't even recognize the person behind the curtain as his daughter-in-law.

The door closed. Through the curtain, she heard the guest enter. Her voice drifted from behind the curtain, sweet and professional:

"Please wait a moment, sir. We're not ready yet. You can change into your bathrobe first. It will be ready soon."
