Valt:
There was bubbles. Lots of bubbles.
"Haha, look we have bubble beards!" Valt grinned.
You snickered. "Beard buddies!"
Shu:
Shu had been skeptical. He didn't really see the joy in staying in a bath longer than he had to for general matinence, but a few candles, some soft music, and a book on battle techniques later, he was having a good time.
Except for when you'd splash him in the face. You couldn't help yourself.
Ken:
He was so embarrassed, despite the fact that you've seen each other naked before. It took a lot of convincing to get him in the shower, but once he was in and allowed himself to look at you, he grew more comfortable.
Now it's become routine, and he won't shower without you.
Rantaro:
He won't stop staring. And groping.
You finally shoved the bar of soap in his mouth when he tried to grop you while you were washing your hair.
Free:
You found that Free really didn't care if it was a bath or shower, as long as you went to the trouble of turning the water on so he didn't have to.
You also took to washing his hair for him, enjoying being so close. And sometimes he'd fall asleep against you.
