After returning to Ou's house.

Ou Mengru sat in the sofa chair in front of the floor to ceiling window in her bedroom. She turned on the computer cross legged and searched Baidu with a nervous heart.

It is more certain that parents with type O blood cannot have children with type a blood.

Father and mother are both type O blood, and she is also type O blood.

But why is my brother type a blood?

He's not a child of the Ou family? Who is he?

Is there something wrong with Baidu?

She clearly believed in the result, but it was difficult to accept.

Ou Mengru took out his mobile phone, turned out the number of a doctor friend and politely asked him for confirmation. As a result, the doctor friend told her very definitely, "Mengru, there is only one possibility, not his own. Children born to parents with type O blood can only be type O blood. "

"Thank you, Dr. Guo." After hanging up his cell phone, ou Mengru has been difficult to describe his mood at this time.

Ouyi was not born by her parents... The secret exploded in her mind like a heavy bomb.

Sitting cross legged in the sofa chair, she was dull.

Unconsciously biting his nails, his good-looking eyebrows frowned very tightly.

Isn't my brother born to my parents?

But how can the first child be adopted?

What's more... My mother was very young when she gave birth to her own age. However, she was only in her 20s and was not too old to bear children. Why should she adopt?

Ou Mengru struggled for a long time and thought for a long time. She didn't find the answer.

Put down the computer, she put on her slippers and went downstairs.

In the living room, Diya has just made herself a cup of medicine and is taking two drinks. She is sitting on the sofa watching TV dramas. Recently, she is not in good condition and the whole person is sick.

Ou Mengru walked towards her and sat down beside her.

"Dreams are like." Diya turned her eyes and looked at her.

"Mom, where's my brother?" Ou Mengru casually took a magazine on the tea table.

"Just now your father called and said that there was an important meeting. He'd better go to attend it, and then he hurried. I may be back later today, so we are the only ones left for dinner. "

"Oh, that..." Ou Mengru was thinking about how to speak.

"Huh?" Diya looked at her. "You're not going out, are you?"

"I'm not going out." She looked up at her, stared into her eyes, and asked in the most relaxed tone, "Mom, what's your brother's blood type, do you know?"

"Type A." Diya answered without hesitation.

"Well, what blood type are you and dad?"

"We are all O-type." Diya answered and found her daughter staring at herself without blinking. She was stunned and met her daughter in shock, as if she suddenly understood the meaning of her words.

In the living room sofa, the two women looked at each other.

"Do you know that parents with type O blood can't have children with type a blood?" Ou Mengru stared at Diya, observed her expression and waited for her answer.

Diya's back was stiff, and the whole person was full of disbelief.

She stared at her close daughter with wide eyes.

"So, my brother is not from the Ou family?" Her voice was light but sure.

Blinking, Diya slowly pulled back her thoughts, "does Ouyi know?" There was some tension in her voice.

Hearing the tension, ou Mengru shook his head, "I haven't told him yet. I just want to ask what's going on. But he knows he has type a blood, and I have type O blood. Because of the blood test report we did together, he may not be so careful and have not noticed it. "
