Minato barged right in, closing the bathroom door behind him.
Not a second thought, not a surprised look, not even an acknowledgement of her presiding space and he starting stripping his clothes in front of the tub.
Minako covered herself as the door flew open, but sighed in relief (and slight annoyance) as it was only her twin who walked inside without warning. "You could have knocked before coming in, you know,"
Minato didn't look up as he kept taking off his clothes; his shirt, his own pair of headphones, his slacks, his shoes, and lastly his underwear. "The bathroom on our floor is under renovations. I figured you wouldn't care,"
It was true, she couldn't deny it. The Arisato siblings typically took baths together when they were growing up. They really thought nothing of it and though the two were polar opposites, they were close enough to not care about bathing with each other. They only started bathing separately when they started living in the dorm.
"How did you know I was even in here? It could have been one of the other girls," she asked and scowled at him.
He shrugged, "I used common sense. I just know," She gave him a look as if didn't believe him. She knew they were twins but they didn't have THAT much telepathy going on. He probably just heard the water running and saw the other girls in the lobby so he knew she was the only one using it. Either that or he really didn't mind popping in "accidentally" on one of the girls. He was practically dating all of them anyway.
Minato slowly balanced himself and walked in, one leg at a time. Then he sat down in the warmth and bubbles. Wait… bubbles? He looked confused and questioned her, "Why are there bubbles in here? And… why so many…?!"
Minako smiled, "You like them? They're supposed to make you feel and smell fresh. Like, invigorate you or something,"
He grimaced, "They're giving me a headache…"
She pouted. Perhaps it was because he was the type of boy who didn't like bubble baths. She splashed a little water at him playfully. He lifted an eyebrow and splashed a bit back. The water war lasted a little while until the two both started laughing (well, more like she was giggling and he was chuckling softly).
She smiled brightly, glad to have someone to play and have "down time" with her. "Hey, how about I scrub your back if you scrub mine? Like we used to back at home?"
He sighed and looked away, as if to think about the proposition. Then he replied, "Sure, whatever," and he gestured for her to turn around, his face all the ambiguous and emotionless as possible. She turned around as he grabbed a sponge, and the two helped each other relax after a long day.
