Before long, a ring that perfectly fit Liang Zhirou's finger was folded.

Liang Zhirou blinked blankly, "Simpler than I imagined..."

Chen Lu curled the corners of his mouth. "It's just origami. It's not difficult at all. It all depends on whether you're willing to learn."

He looked at the ring in his hand, never expecting that he had inexplicably figured out Liang Zhirou's exact finger size, and something just felt off.

"I want to try it too."

The girl got out of bed, and the duck sat on the bed, taking a piece of unused paper next to it and folding it by itself.

As time went on, the girl's smile gradually faded, and her gaze became increasingly vacant.

Oh no, it seems my brain has learned it, but my hands haven't...

"I'll teach you one more time." Chen Lu always had inexhaustible patience with Liang Zhirou, and he demonstrated it again.

Unfortunately, Liang Zhirou was still learning very slowly, so Chen Lu had to extend his hand and let Liang Zhirou fold the folding cloth while he taught her step by step.

After wasting countless sheets of A4 paper, Liang Zhirou finally managed to fold a piece that was reasonably presentable.

With a slight smile on his face, Chen Lu waved goodbye to Liang Zhirou and quietly watched as the girl quietly closed the door.

His smile was gentle, but his eyes were full of the joy of a successful plan.

......

When Liang Zhirou returned to her room, her clear and beautiful eyes were fixed on the ring in her palm, and it wouldn't be an exaggeration to say that her eyes were shining.

These past few days she had been worried about what to do if the engagement ring size wasn't right, and she was also concerned that if she tested him too obviously, Chen Lu would notice something.

I secretly measured it while Chen Lu was asleep, afraid of being discovered...

I didn't expect it to be solved so easily.

After that, all you need to do is buy a nice ring based on the size determined by this method and prepare to propose.

Just then, Chen Mo's teasing voice suddenly came from in front of him.

"I just taught you some tricks before I went to bed, and you used them right away tonight?"

Liang Zhirou was startled, and after a couple of seconds she patted her chest and whispered, "When did you wake up...?"

Chen Mo rested his chin on his hands, lying on the bed, and lazily yawned. "I've always been a light sleeper. I woke up as soon as you left the house."

"I'm sorry." Liang Zhirou felt guilty and a little embarrassed. Didn't that mean her secret rendezvous with Chen Lu in the middle of the night was exposed from the start?!

"What's there to apologize for? Sister-in-law, tell me quickly, were you trying to trick my brother just now?"
