you were working at bubu's pharmacy as baizhu's assistant

today, you were rearranging stuff, when suddendly, you felt shivering and something run down your spine

changsheng, rolled up in your collarbone like a scarf, playfully teasing your neck with it's fangs

suddendly, you felt two strong arms wrap around your waist and baizhu's hot breath tingle your neck as he grunts in your ear with his low calm voice

"be careful, darling, or changsheng won't be the only one biting you tonight~"
