Rachael widened her eyes in shock. "No, that is not what I meant." Without giving him any time to misinterpret her words, she quickly explained, "Since I am shorter and smaller than you, I think it will be more convenient if I take the couch and—"

"I have some pending work to finish, I'll be in the study room." He then grabbed his nightwear from the wardrobe. "There is a washroom there as well, I'll take shower there." 

Without waiting for her reply, he walked out.
