Mac Trong was reading the newspaper while waiting for Luc Nha to finish cooking a few simple dishes for dinner. Although his family was well-off, he never intended to make his cozy life any different from usual. He still lives in a house big enough for two people, still eats meals cooked by his wife, occasionally takes his wife to the supermarket to shop, and listens to his wife talk about his son's education. 

But lately it seems like his wife has been hiding something from him, the evidence is that the rice she cooks is sometimes dry, sometimes mushy, the food is sometimes salty, sometimes sweet, the house is sometimes clean, sometimes not, and sometimes she doesn't even hear what he says.

Mac Trong flipped through the newspaper while glancing at Luc Nha's back and asked quietly: 

- I heard that Tu Huan was in the hospital, have you come to visit him yet?

Luc Nha was a bit startled, a stalk of fried beans was thrown out of the pan. She turned off the stove, waited a while before answering: 

- I haven't visited yet. On Sundays, the kids often go out, maybe the old illness probably comes back. 

- Anyway, you should come visit a little. - Mac Trong reminded. 

- I know. 

Luc Nha put the food on the table, gave Mac Trong a bowl of rice, and placed the chopsticks neatly in place. Only then did Mac Trong put the newspaper aside and asked while eating: 

- I heard you let someone into Tu Huan's house again. 

Luc Nha smiled: 

- As the child of my best friend, Tu Huan is also of age, I'm worried that he won't be like other people. 

- If that family doesn't have any opinions, that's fine. But you already brought someone here before, is that convenient? 

- No problem! The previous person was just a maid. This person is the right person to marry. 

Mac Trong evenly said: 

- I heard the driver say that yesterday Lam and this new girl went separately to Tu Huan's house. Not knowing what to do, she fell and hit her heads and were hospitalized that night. 

- What? - Luc Nha stood up. - Let me go visit her and see.

Mac Trong gently advised: 

- Finished eating and then left. There is a doctor working there, you don't need to worry too much. If there's anything, ask your friend to come with you. I'll feel more secure. 

Luc Nha quickly stopped being impatient, calmly sat back at the dining table, slowly picked up food for her husband, and said: 

- I know. You also eat a little more, you've become thinner lately. 

Mac Trong nodded: 

- Someday I will go to Tu Huan's place to see what happens.

Luc Nha's gaze was slightly stagnant. Mac Trong said he would visit Tu Huan? 

Then Luc Nha stiffly smiled, gently holding Mac Trong's left hand resting on the table: 

- I will go with you.

It was night time, Mac Tu Huan was still sitting on the bed, attentively looking at his phone. Thuc Nghi has been gone since last night, has not returned all day, Mac Tu Lam is nowhere to be seen, only Truong Tinh Han comes in the morning to bring breakfast, at noon to bring lunch, and in the afternoon, come back to bring dinner. 

Truong Tinh Han took back Mac Tu Huan's phone. When she saw him bewilderedly looking at her hand, she smiled and coaxed: 

- It's time for class. Once you've finished all the exercises, I'll open the animation again for you to watch!

Mac Tu Huan neither nodded nor shook. Truong Tinh Han just opened the exercise book and laid it out in front of him, along with a pen and eraser. Mac Tu Huan did not want to do his homework, stubbornly pulled the blanket over his head and lay quietly. 

Truong Tinh Han sighed. In fact, no matter how much he does his homework, he won't get any better. Just because he's of school age, he still has to go to school, but no school wants to accept a student who can't graduate. There is also no teacher who has the patience to teach and re-teach calculations that even if he does it a hundred times, it will still be as wrong as the first time. 

Truong Tinh Han patted Mac Tu Huan's shoulder through the thin blanket and asked: 

- How were you going today? Are you sad about something?

Mac Tu Huan still refused to budge. Truong Tinh Han also took the opportunity to be angry: 

- Then I won't play with you anymore. I only hang out with people who study hard! If you don't study, I'll go find another friend to play with. I won't stay with you anymore. 

Mac Tu Huan curled up like a boiled shrimp, still refusing to open the blanket to look at Truong Tinh Han. 

Truong Tinh Han was about to go out, so she turned around and announced: 

- I'm going! 

Mac Tu Huan still said nothing. Truong Tinh Han emphasized again: 

- I'm really going! 

Stupid Mac Tu Huan! If he doesn't see her for a long time, he'll have to go look for her himself. Truong Tinh Han instructed the nurse to keep an eye on Mac Tu Huan's hospital room, contact her immediately if anything happened, then go straight without looking back.

Truong Tinh Han did not leave her backpack, so it seems that she will not return soon. Mac Tu Huan sat up and reached for the phone to call Mac Tu Lam, but after calling several times, his younger brother did not pick up the phone. 

Maybe something happened. Mac Tu Huan opened the photo on his phone again and looked at it. Yesterday he took a photo of a few pages in Truong Tinh Han's notebook, staring at the words neatly written in ink: "Duong Thuc Nghi moves to Mac Tu Huan's house for three days, Mac Tu Huan must hospitalize." 

If he remember correctly, Thuc Nghi moved to his house the first day at noon on Friday, on Saturday morning she had a fever, and then on Sunday morning she went to the park to play, exactly on Sunday he had to be hospitalized. If calculate roughly, it can be considered that it has been three days. But what day did Truong Tinh Han write this line? Why write like that? There are also the words "Truong Tinh Han moved to Mac Tu Huan's house". The pages have words very far apart, but there are many pages with traces of pen and no ink.

The words "Thuc Nghi fell down the stairs, lost her memory" are fainter than the other lines. These are all real events that happened. The problem is that it seems that Thuc Nghi did not completely lose her memory, she just recovered quite slowly compared to Cao Truc's prediction. 

Mac Tu Huan flipped through the photos while thinking, wondering how Thuc Nghi is now. Both Thuc Nghi and Tu Lam were under his care when they were young. Although they only met until they were six years old, he always considered Thuc Nghi as his younger sister and did not want Thuc Nghi to suffer any harm because of him. 

Outside on the balcony, suddenly there was a soft sound of a cat meowing. Mac Tu Huan put the phone under the pillow and quickly went to open the door. Thuc Nghi's black cat sneaked into the room, ran straight out and scratched its claws at the main door. Mac Tu Huan understood, so he opened the main door slightly to let the cat out. The cat looked back for a moment. When it was sure he was following, it continued to hide through potted plants and under chairs to another hospital room.

Mac Tu Huan opened the door, quickly went to the hospital bed, and was surprised to see Thuc Nghi with a bandage wrapped around her head. The previous wound had not yet completely healed, so unexpectedly she was hit again. 

- Thuc Nghi. - Mac Tu Huan called softly. At that moment, Thuc Nghi opened her eyes. Mac Tu Huan was startled and stepped back a little, just enough for Thuc Nghi to reach his shoulder to grab him. 

- Huan! It's grandpa!
