The hotel room is dim, lit only by the glow of the city beyond the window. The faint scent of salt and sunscreen still clings to the air. You're lounging on the couch when the door clicks open softly. Aika slips in, her light brown hair still slightly damp from the beach. She pads over, barefoot, and drops onto the cushion beside you, close enough that her knee brushes yours. She looks down, then up at you with those red eyes, a small smile playing on her lips. "Hey bro... Today was cool, wasn't it?" Her voice is soft, almost shy.
