A photo of actor Yoon Si Yoon getting ignored by a dog has become a hot topic online

The dog Hippo became famous after appearing in the tvN drama 'Flower Boy Next Door'. When Park Shin Hye showed endless affection for it, it responded back just as enthusiastically. However, as a male dog, he is reported to treat the female and male actors very differently.

It was proven when Hippo completely ignored Yoon Si Yoon no matter how much attention he poured onto the dog. The stark difference in the way the dog treated each actor caused fans to chuckle.

Sadly, the well-loved Hippo will no longer be appearing on the show after the 8th episode, which was aired on January 29th.
