When Heiyan said that Si Tong's teacup turned off, Yuxing, standing on the roof of the building opposite the window, frowned coldly and frowned deeply.

Black Yan suddenly felt a chill behind him.

"Elder sister, who are they?" Si Han wanted to shout to catch the thief, but Si Tong seemed to know Heiyan and Yuxing standing on the opposite roof, so he swallowed the cry back to his stomach.

"I don't know." Si Tong took back his tea cup. He just blinked and lied. He didn't seem to care what Heiyan said.

If the person who just stole her tea cup was not Heiyan but Yuxing, she couldn't find her Yuxing hidden in the toilet.

In other words, Heiyan was not strong enough and betrayed Yuxing.

However, when Si Tong dropped the short word "don't know", Yu Xing, standing on the opposite roof, his red blood eyes were deeper in the dark night.

It's like a raging lion in a rage.

"Steal? Steal what? There are thieves? Dare to run to my sister's room and bully my sister. My brother told you to be a new man!"

When the door of the next room opened, Si Chen rushed from his bedroom.

When Si Han heard Si Chen's voice, he turned his head and looked out the door. He saw Si Chen holding a long pillow and rushing into the door, waving a rectangular pillow and throwing it all over the room.

"Eh, where are people?" he shook his pillow twice. When Si Chen saw that his sister's bedroom was empty and there was no figure, he was stunned twice.

Did he hear the sound? How can people disappear in the blink of an eye?

When Si Chen rushed into the house, Si Han turned to see Si Chen. Unexpectedly, later, she couldn't see Heiyan. She hurried to look out of the window, but saw the mysterious man standing on the roof of the other building, who had disappeared.

On the desk, the tea cup that Wu Jinhua bought for Si Tong today is still there, but the two people who stole the tea cup are gone.

"Elder brother, you should have heard wrong. Go back to the house and sleep." Si Han didn't tell Si Chen what had just happened in the house.

"Really all right?" Si Chen scratched his scalp. Did he hear wrong just now?

"It's all right." the Secretary's letter drove away the Secretary Chen.

She is a smart girl. Naturally, she knows at a glance that the two men just now are not thieves. They should have come to her sister Si Tong.

After knowing that Si Tong is not his own sister, Si Xin has never asked Si Tong more about some things, especially just now, in front of Si Chen, she also covered Si Tong.

When Si Chen left, Si Han didn't ask anything. She didn't mention anything about what happened just now.

Because he used to take the lead in dealing with her and wanted to embarrass her. Why did he leave a note today saying he wanted to help her?
