Yun Zhu had turned around abruptly because he wanted to ask both Yun Jian and Si Yi if the house he built or Duan Li built was nicer. It was just that he was greeted with the sight of Yun Jian sitting on Si Yi's lap before he could get his question out.
"Yun Zhu, why are you…" Out of curiosity, Duan Li turned around as well when she caught Yun Zhu going silent after he turned out of the corner of her eyes.
Duan Ya mimicked Duan Li and turned around as well.
However, Yun Jian had already hopped off Si Yi's lap as the latter ceased trapping her. Duan Li and Duan Ya, thus did not catch the suggestive scene of Yun Jian sitting on Si Yi's lap.
"Cough, nothing." Yun Jian pretended like nothing happened, not before she glared at Si Yi. When her big eyes widened in threat, it only sparked the flicker of itch within Si Yi further, but Yun Jian had already gone downstairs.
