Yeonjun is a young veterinarian whose clinic is frequently visited because he is very professional. Yeonjun knows many tips for taking good care of pets and even checking their health and their comfort well. Because Yeonjun is someone who loves animals. Most customers came to check the health of their pets, but one day Yeonjun was told to poison the pets.

"Your dog is fine, he is very active. But my advice, before your dog eats anything, You have to make sure what he eats is safe, or he will get poisoned." Yeonjun said while glancing at his customer's boyfriend.

Last week that innocent girl also came to the clinic with her boyfriend, and without her knowing her boyfriend asked Yeonjun to inject poison into her dog with the promise of money. Yeonjun received the money and provided his services to the girl for free last week. Instead of injecting poison, Yeonjun injected the best health vaccine.

Today the girl came with her boyfriend again, telling him that her little dog had just stepped on a needle.
