And so, the Lu Xingyan and Han Yehan followed the treacherous man out of the campus, following him and the girl he flirted with around the town. When they saw them heading to a motel, Lu Xingyan readied her phone and took a photo of them entering.

She dragged Han Yehan and by the time they entered, they saw Fan Jingli and the woman he was with, in the elevator.

She quickly went to the counter and told the staff, "Excuse me Ms, can we rent the room next to the couple who just left?" She pointed at Han Yehan and herself.

The woman blinked a few times upon seeing a cute bespectacled boy but when she saw another cool-looking guy standing behind him, she blushed lightly. "Oh sure."

Since Lu Xingyan was in a hurry, she didn't notice the way the female staff looked at her and Han Yehan. On the other hand, Han Yehan noticed it, making him suddenly feel embarrassed. He wanted to say that he was not gay and the boy with him actually was a girl but he couldn't just say that. He ignored the woman when Lu Xingyan rushed to the elevator. He didn't like how others were looking at them, good thing he was wearing a mask.

"Oops, sorry." Lu Xingyan apologized after crashing into the housekeeper.

"Ah... it's alright."

She bowed at her before they entered the elevator and arrived shortly arrived at their designated floor. They went out and stood in front of the room which Fan Jingli rented.

"Are you sure it's this one?" He asked. "It can be the other one."

"The lights are on." She pointed at the small space between the lower part of the door and the floor. "While the other one isn't." She added.

"Oh... Well? What should we do now? You don't plan on barging in do you?" Han Yehan asked, crossing his arms.

Lu Xingyan pursed her lips since she was actually planning on doing that. She wanted to catch Fan Jingli on the act and take photos just so she could send it to see her sister.

"You can't be serious, right? How can we even enter the room when we don't have a keyca-"

Lu Xingyan raised a card and guiltily said, "I kind of stole it from the housekeeper..."

He sighed and shook his head a bit. "Think of something else. You don't want to corrupt your eyes by seeing them in the middle of it, right?"

She heaved out a heavy sigh and turned to him, "Then what do you suggest?"

"Something less troublesome." He leaned against the wall, looking at her, waiting for her to think of something. She was the mastermind and he was just her underlying. He was on a neutral side that was why he chose not to suggest anything since he didn't want to be blamed later if their plans didn't work out.

Her lips were stretched into a thin line as she tried to think of another plan. "How about I call my sister here? We already rented a room. We just have to wait for them to come out."

"Do you think she can wait? Knowing her, she would probably barge in as well just to prove you wrong." He countered.

Lu Xingyan knew that he was right since she knew her sister the best. She moved her gaze to her wristwatch just to check the time. "From an article I read, they surveyed 4,400 customers and found that for most heterosexual couples, sex lasts 19 minutes on average, and it consisted of 10 minutes of foreplay and nine minutes of actual intercourse." She said with a serious look on her face.

Han Yehan: "..." Who cares about that?

She turned her intense gaze to him, "Can you pick up my sister at school? I will wait in the room. I'm pretty sure that by the time you come back, they're done. You might even catch them in the elevator."

Seeing them in the motel itself was good enough, right?

"Are you really going to do this?"

"Yes. I rather have my sister hurt now than later on. For now, while I'm waiting, I'll make sure to think of something as payback on that." She was not going to let this go easily. She wanted to make sure that a man like him would rot in hell. His biggest mistake was not taking her sister seriously.

Han Yehan sighed. Well, at least this was a better plan than catching the bastard on the act.

"Oh, don't forget to call me once you're about to enter the building."

...

When Lu Xingyan received a message from Han Yehan, she went to the lobby and met up with him and her sister.

"Huh? Why are we here?" Lu Weichun asked, looking at them in confusion.

Lu Xingyan took her phone out and showed the photo she took earlier to her sister.

Just as expected, Lu Weichun's eyes went wide in shock. "N-no... This can't be..." She turned her wide eyes to her sister, looking at her in disbelief.

Lu Xingyan raised a brow. How can her sister be an idiot? Was she even her sister?

"You still won't believe even with this proof? Don't be ignorant all your life! Can't you at least take a day off?"

Just before Lu Weichun could open her mouth and say something in defense, Han Yehan caught her up to it, grabbing their attention when he said, "Oh wow. They really went out as expected."

They both followed his gaze and saw Fan Jingli with the girl. His hand was placed on her waist. The girl laughed when the guy said a joke.

Lu Weichun stood on her ground, frozen when she saw the two with her own eyes.

On the other hand, when Fan Jingli turned his gaze away from his companion, the first person who caught his attention was none other than his 'girlfriend', making him stop in his tracks. "Weichun?"

The girl stopped as well, turning her head to him, confused. He looked like he had seen a ghost because of his pale complexion. She noticed that his attention was somewhere else that was why she turned only to see the trio standing nearby.

Fan Jingli quickly lowered his hand away from the girl's waist before taking a step closer to Lu Weichun. "W-Weichun, I can explain."

Lu Xingyan scoffed loudly, "Have you considered suing your brain for non-support?"
