What does an unmarried man know?

"Sis, are you crazy?" Axel gasped in disbelief after hearing what happened between his sister-in-law and brother last night. "Why would you ask him such a stupid question?"

Heaven pressed her lips into a thin line, glancing at Axel and then at Ivy. Even though the party last night ended, many of the older relatives stayed in the old residence. Thus, the mood somehow gave off a continuation of last night. Since the elders, including Lionel and Ria Zhu, planned to go fishing, everyone came. The old residence was big enough and had a pond for fishing, after all. 

While Dominic was spending time with the relatives and his parents, Heaven and Axel stayed in the tent. The latter noticed that Heaven was giving her husband a cold shoulder; it wasn't obvious, but for someone who was very close with the couple, Axel knew something was wrong. 

And he was correct.
