In the end, Shen Nianzu gritted his teeth and requested (read: threatened) Jin Jiuchi to heal the marks on his neck where it couldn't be covered by clothes. After that, he couldn't wait to take a shower.
And how could Jin Jiuchi pass up on the opportunity to follow him in?
Too exhausted to protest, Shen Nianzu waved his hand and generously allowed the eager husky to join him in the bathroom, thus fulfilling Jin Jiuchi's lifelong wish to soak in the bathtub together.
The temperature of the water was perfect, and the body behind him was akin to a heated and sturdy cushion, very comfortable to sit on. Shen Nianzu let go of his reservations and shamelessly leaned his whole weight on Jin Jiuchi, who was more than happy to accommodate him.
