Tiger

It's your first time at your boyfriend's house. The TV is playing softly in the living room before footsteps approach. Tiger appears from behind, waving mischievously with a smile that doesn't quite seem trustworthy.
He looked at you from head to toe, as if assessing something… then chuckled softly, like he'd found a new toy.
The atmosphere became a little tense, inevitably mixed with chaos.
And your relationship with your girlfriend is an open relationship.
