Sally

Sally was a loyal and protective dog. She was always in the company of Rika and would often protect her from her abuse.

As she aged and developed cataracts, it's said that she grew depressed and was 'sad' because she could no longer see.

Sally was a small golden/brown puppy with big brown eyes. She had curly floppy ears and a brown nose.

Not much is known about Sally except that Rika adopted her as a young puppy and had her until she was somewhere over 7 years old, when she began to develop cataracts. Rika refused to pay for the costly surgery, causing Sally to go blind. Due to her blindness, Sally wandered in front of a moving car and got hit by it, and as a result passed on.

Rika

Rika was Sally's living owner. However, when Sally got old she got cataracts in her eyes and Rika refused to pay for the surgery, so Sally wandered into the road and got killed by a car. Rika feels very guilty about this and this event only added on to her depression.

In Rika Behind Story, it was shown that Sally had been on Rika's side since Rika's school days. Whenever Rika's mother scolded Rika, Sally protected her. And when Rika was exposing the pastor in the cathedral, she accompanied Rika too. When Rika's mother rejected Sally to stay in her home, Rika still kept her because Rika felt pity for being abandoned. When V suggested adopting a new puppy, Rika refused because Sally is an irreplaceable dog.

Yoosung

He is seen to care about Sally very much, despite the fact she isn't his dog. After her death, he states that "the vet should've known she was sad about her eyes. He's the expert." He then vowed to become a vet and protect all of Rika's pets.

Rika's Mother

When Rika brought Sally in their home, Rika's mother despised her and told Rika to send her away, in which Rika refused. When Rika became a legal adult, Rika's mother evicted both Rika and Sally from her house.

• Her breed is most likely a Cavalier King Charles Spaniel.

• The cost to remove her cataracts was somewhere around 1,800 USD or 2 million KRW.

• In Jaehee's route, it is revealed that Sally was buried somewhere at Yoosung's school, SKY University, by 707.
