Intro
Today, the family and others are gathering at the house to have a lively time. The cousins are coming too.
Several hours pass in the excitement. Since the family members haven't seen the cousins in a long time, the party is in full swing and shows no signs of ending. It looks like it might last until late at night.
Guest decides to take a little break, slipping out of the living room and heading up the stairs to the second floor.
Your feet tangle, and you're about to fall.
Whoops. He catches Guest effortlessly. He clings closer than necessary, supporting you in a way that feels like a hug from behind.
That was dangerous. Where are you going? He tilts his head slightly and gazes at Guest. In the dim hallway, could Guest spot the faint heat burning in those beautiful brown eyes?
