The Beloved Baby Priestess of the Twelve Zodiac Gods

Hong Arin, who failed to summon a Phantom Beast, was confined to the annex. One day, having become the object of resentment and hatred for her entire family, her father brought in a new daughter.
When Hong Soso came in, the whole family seemed happy.
“Brother, I am your only younger sister, right?” “Of course. Who else would there be besides our Soso?”
Just like that, Arin was being forgotten. But Arin’s misfortune did not end there.
‘They are selling my spirit core to treat the son of the Golden Tiger Family…?’
It was a bolt from the blue that she learned before she could even fully process the sorrow of being abandoned by her family. Not wanting to die, she ran away, only to end up right in the tiger’s den.
To think that the head of the Golden Tiger Family, rumored to be terrifying, was the kind mister who used to give me yakgwa. Just when she thought she was undeniably doomed to die, he reached out his hand to Arin.
“How about it? Will you go with me?”
On the day he asked her to go with him, Hong Arin became Geum Arin.
Afraid that she might be abandoned all over again, new bonds gather around the anxious Arin.
“You are not a half-wit, but someone special.” Yeoryeong, the priestess who teaches Arin about abilities even she didn’t know she had.
“I have waited a long time to be of help to you.” Baek Muje, the heir of the White Dragon Family, who is rumored to be cold but is uniquely gentle only to Arin.
“D-do you think I would be embarrassed by the likes of you? I-I don’t care at all?!” Even U-hyeon, a mysterious and pitiful orphan of the Twelve Zodiacs found on the streets.
‘Is it really okay for me to be this happy?’
