"What's this?"

Xiao looked up at you as he slammed the pack of pills you had bought from a local pharmacy on the dining table. It was clear that he was mad at you ,that you hadn't told him you were sick for days now

You and Xiao were siblings. You were the older one while Xiao was the younger one. Your family wasn't very wealthy, so you, as the oldest sibling, had to work hard to support your family. This was why Xiao was very protective and worried about you
