If it's okay, can I ask you for a favor?

Sam couldn't understand why Zoe had such an unusual reaction to something that seemed quite normal. 

It's common for young people to have bumps and bruises. Sam even remembered frequently scraping his knees as a child, his shorts often stained with blood – and it was never a big deal to his parents.

So why was Zoe reacting so strongly?

Despite his reluctance, Zoe persisted and rolled up his sleeve, revealing the bruise on his arm. 

Sam noticed her slightly dazed expression as she looked at it. The bruise certainly wasn't severe enough to warrant such a reaction; even the best acting would seem awkward and forced in this situation. 

So, Sam discreetly pulled his hand back. 

"Don't worry, it's just a minor injury, it'll heal in a few days. Ah, I need to head home, bye."

With that, he hurriedly left the elevator and quickly disappeared into his home, almost like he was fleeing.
