The two were talking in the dormitory when they suddenly heard a knock at the door.

While talking to Cai Youyou, Hua Xi opened the door to take a look, but she didn't expect that it was her mother who came.

"Mom, why are you here?" Hua Xi asked with some surprise.

"It's a pity, it's your birthday this week. Mom happened to be running errands in the neighborhood today, so she came to see you and asked if you had anything you wanted to eat, so that I could go back in advance to prepare. Hua Xi's mother said with a smile.

Seeing the happy appearance of Hua Xi's mother and daughter, Cai Youyou's heart was faintly sour.

She vaguely remembers that when she was four or five years old, her parents also helped her prepare for her birthday, and the family of three was also so happy.

Until she was three years old, her father would go out a lot, and her mother would stay at home. Until she was four or five years old, her mother would sometimes leave with her father and go out for a few days to leave her in the care of the family's virtual housekeeper and robot nanny.

One winter when she was five years old, one day, while she was studying under the care of a virtual butler, her father suddenly returned home.

Although she was only a child of less than six years old, she clearly remembered that her father's face was ugly, and that the beige wool coat he was wearing had a large dark red blood stain on it.

Her heart suddenly tensed.

She remembered that her mother was out with her father, and she couldn't help but look at her father and ask him about her whereabouts.

Cai Zhe, who was weak, raised his big hand that was a little rough and stroked her head.

She suddenly had a bad feeling in her heart.

She knew that her mother would most likely not return.

In the next two years, her family really lost its former laughter.

Her father was always alone in the secret preparations and would leave the house from time to time.

Sometimes he would call two uncles she didn't know and discuss something with them.

Later, when she was seven years old, her father went out again. By the time she saw her father again, he had turned into a cold, white corpse.

The birthday of the year she was five years old was her last birthday and the birthday she will never forget.

Hearing that Hua Xi's mother was helping her prepare for her birthday, Cai Youyou's heart couldn't help but think of a lot of past events.

Just when she was thinking nonsense, Hua Xi suddenly laughed, pulled her arm and said, "Yoyo, I have been a leather monkey since I was a child, and I rarely have female friends." You are my first best friend. This weekend, will you accompany me home for two days and spend my birthday with me? ”

Cai Youyou was stunned.

When she was in Zi Chenxing, she didn't even have a friend, and even the second uncle's family was afraid to avoid her when they saw her.

Attending a friend's birthday party was something she had never done before.

Cai Youyou, who originally wanted to use the rest time on the weekend to study the soil in the laboratory, couldn't bear the pleading of Hua Xi, so he nodded and agreed.

In the afternoon of this day, Cai Youyou went to the outdoor goods store on the commercial street near the college under the pretext of going out to buy something, and bought a pair of outdoor gloves for Hua Xi that she had already taken a fancy to the Internet as a birthday gift.
