When Raelle wanted an answer, she'd do anything to find that answer for herself. And currently, she was doing exactly that. She followed Shui Xian around as she kept asking, "What did he mean?"
"There is no meaning other than the one you understood," saying that Shui Xian entered the bathroom to avoid answering her but he really was forgetting who his wife was. Because Raelle followed him even inside the bathroom without any care.
Raelle trapped him against the basin and said, "Then why do I think there was another meaning behind those seemingly simple words?" She took a pause and went on, "If you won't answer, I'll have to look for someone who is willing to make me understand."
Shui Xian held her shoulders and tried to look for the right words. "Mmm... Save water and save time means he suggested we should take a bath together."
"Oh!" Raelle had a look of understanding. "That's actually a good idea."
