He Teng was indeed very strict with He Zhilan.
He Zhilan has a bit of a cleanliness obsession, but because of He Dongxue's instructions, He Teng firmly refused to let He Zhilan bathe with water until He Zhilan complained that she was so uncomfortable she couldn't sleep. Only then did he grant her a basin of hot water for a wipe-down.
"Brother~" In the evening, He Zhilan snuggled into He Teng's arms, and her hands, which were a bit cold during winter, were now placed on his body, letting her icy hands rest against his warm chest.
Hearing He Zhilan calling him, He Teng's eyes drooped and he grunted in acknowledgment.
"Can't you smell something foul? Sniff this~" He Zhilan shook her hair in front of He Teng's nose, "I haven't washed my hair in more than twenty days~ Are there bugs yet?"
