Welcome is set to air in March of 2020 on KBS. One of the kdrama of 2020 that I really want to catch.
The drama is about a cat who can transform into human for his owner to stay by her side and start living double life as Hong Jo (L, Kim Myung Soo). Kim Sol Ah (Shin Ye Eun) has a puppy-like human character who loves people and always want to protect her love ones. They cross path when Sol Ah brings Hong Jo home thinking he is a cat.
Other cast includes Seo Ji Hoon, Kang Hoon. Yoon Ye Joo and Kim Yeo Jin.
