In just a few seconds, a gentle smile appeared in Devin's eyes.

Su Nan thought to herself that she must have been seeing things, otherwise how could she have seen the teacher's eyes full of scheming?

The car stopped in front of the Su family's gate, and Butler Su hurriedly came out to open the door.

Winters in Fujishi are damp and cold, and his knees were a little sore, so he slowed down after walking a few steps.

He smiled broadly, but when he looked up, he saw Devin's greedy gaze, and his smile froze in his eyes.

Does this person... have two faces?

Doesn't the young lady know?

When Butler Su came to her senses, Devon had already returned to normal and was helping his wife out of the car.

He trusted his intuition; there was something strange about the professor and his wife, they didn't even seem like a married couple.

What couple keeps their distance all the time? They're foreigners, after all.

Su Nan: "Why did you come out to pick me up? It's so cold outside."

Butler Su smiled and nodded to the couple, "They should have come out to greet them."

He didn't show it on his face, but he was inwardly very flustered.

This young lady is letting a wolf into the house...

Fortunately, the old man has always had a good eye for people.

Butler Su stepped aside to let the guests and the young lady go in first, then followed, turning around in the corridor and heading towards the old man's room.

Tengshi has no central heating; people rely entirely on charcoal fires for warmth. When there's nothing to do, Grandpa Su usually doesn't go out, and even food is delivered to his house.

He's getting older, and he doesn't walk as nimbly anymore.

If it weren't for New Year's Eve, he wouldn't have dressed up and gone out to eat with everyone.

He heard that his granddaughter had invited guests today, so he dressed up a little more formally.

"Master," Butler Su said, slightly out of breath, clearly having jogged over.

Grandpa Su said, "Can I fly away? You run so fast, be careful your bones don't break."

They were about the same age, but Butler Su was in much better health than him.

After sitting down, Butler Su took a sip of the hot tea that the master had handed him before speaking.

"The foreigners brought by the young lady..."

He simply stated what he had seen and waited for the old man to make his own judgment.

Butler Su always kept to his duty and never interfered in matters that were not his responsibility.

Grandpa Su is not senile yet; he doesn't easily speculate about others, but he also doesn't easily trust anyone.

The young lady had mentioned her teacher and his wife to the old man many times, but he had never thought of inviting them to his home.

"Old Su, you stay here and keep an eye on things for a while. I'll observe for a bit longer." Old Master Su's heart skipped a beat, and he was basically certain of the old butler's idea.

The butler grew up with him, received the same education, and served him for decades.

He had learned about seven or eight parts of the Su family's ability to judge people, but he never overstepped the bounds.

The granddaughter probably didn't even realize it when it was brought up this time.

…

In the hall,

Divin subtly inquired about the formula for the skin repair lotion.

Su Nan assumed he was satisfied with the repair lotion, so she offered, "I've already had someone buy ten boxes of repair lotion from Lin Yan Pavilion, but they won't be able to deliver it to the school until after the New Year."

A cold glint flashed in Devin's eyes, but before the smile on his lips could fade, he nodded.

Old Master Su and the old butler listened in the back with trepidation.

Can't your granddaughter see through such an obvious test?

Skin repair lotion formula?

That was passed down in the Lin family. Was asking the Su family a test or something else?

When Old Master Su realized why the Lin family had suddenly moved away from Teng City, his expression changed instantly.

He stepped into the main room, his expression solemn, devoid of his usual gentleness.

Su Nan's eyelids twitched. Did her grandfather dislike foreigners?

"Teacher, this is my grandfather."

“This is my teacher, Devin…”

Su Nan introduced the two to each other, while constantly giving the housekeeper meaningful glances.

But the butler didn't look at her; instead, he subtly observed Devin and his wife.

The main room of the Su family's house is furnished with mahogany furniture. Now that it's cold, the chairs have been covered with red and yellow cushions.

"Hello, Mr. Su." Devin nodded to him with a gentle gaze.

His smile was genuine, but Old Master Su was terrified.

This person looked very familiar to him; he resembled the foreigner who used to buy recipes from the Lin family's shop.

"Hello." After greeting everyone, Grandpa Su sat down to drink tea.

This meal might be hard to swallow today.

Su Nan watched anxiously from the sidelines, and could only smile and try to find topics to chat about with the teacher.

Fortunately, dinner was served quickly, and she breathed a sigh of relief.

Devin and his wife remained calm, as if they hadn't been slighted, but they didn't initiate any conversation.

Throughout the meal, Grandpa Su didn't say a word and left as soon as he finished eating.

His son and daughter-in-law aren't home tonight, so he has even less appetite.

Su Nan assumed her grandfather was tired and didn't dare to ask any more questions.

After seeing Devon and the others off to their car, she turned around and was startled by the butler waiting behind her.

"Miss, Master is waiting for you inside." Butler Su nodded solemnly, then turned and walked away slowly.

Su Nan raised an eyebrow and followed.

A cold wind was blowing, so she pulled her coat tighter and quickened her pace.

The weather in Fujishichi changes very quickly; it gets cold suddenly, without any transition period.

Grandpa Su sat around the stove and set up a game of Go.

That person must have come for the Lin family's skin repair formula.

He carefully recalled what Devin had said, every word of which was about the formula. His purpose was so obvious, so why hadn't his granddaughter noticed?

"Grandpa, it's so warm here." Su Nan walked into the inner room and was immediately enveloped in warmth.

The thick barriers immediately closed, blocking the cold air from behind.

After Butler Su came in, he poured a cup of tea for each of them and then stood to the side.

Grandpa Su lifted his eyelids and slightly raised his chin, gesturing for her to sit down.

Su Nan pursed her lips, sat down on the cushion, and waited for her grandfather to lecture her.

She's gotten used to her grandfather striking a pose every time he's about to lecture her.

Butler Su shook his head helplessly, offering no advice whatsoever.

"Did you buy repair lotion for those two foreigners?" Old Master Su asked calmly, his eyes sharp.

Su Nan felt a chill run down her spine. This wasn't the first time she'd seen that look in his eyes; her grandfather would only act like that if he was truly angry.

She nodded stiffly.

"Why did you buy it?" Grandpa Su asked patiently.

Su Nan briefly described the skin injuries her teacher's wife sustained after the car accident.

"Don't buy it anymore. Return those ten boxes of repair lotion. His wife's skin has already healed." Old Master Su's expression remained indifferent.

Some things don't need to be said too explicitly; with my granddaughter's keen senses, she must have noticed something was wrong.

Su Nan paused for a few seconds, then pursed her lips and didn't answer.

She had already promised to give it to him, so why would she suddenly go back on her word?

After the Lunar New Year, Lin Yan Guan's repair lotion will be subject to purchase limits.

It's impossible to buy ten boxes at once.

Grandpa Su continued, "Just because you never suspected Devin doesn't mean they didn't have problems."

They are not a couple.

Su Nan turned to look at Butler Su, her eyes filled with shock.

What else could they be but husband and wife?

She thought about it carefully but couldn't find any flaws.

"If you don't believe me, find an opportunity to test me, but you'll need a bodyguard with you recently." After saying this, Mr. Su picked up a black piece and placed it on a spot.
