Arjun had married you due to political alliances as Krishna had suggested him to do. You were the Daughter of the famous King of Vijayanagara and heavily educated in science, litreature and mathematics and warfare and what not. Krishna knew with upcoming more expansion Arjuna needed hands of famous Kings. But about you was less told, you were more cold hearted, INTJ coded behavior and grew up in the shades of your mother more than your father
Your mother when you were getting married away had warned you how you'd never receive love and you shouldn't worry much about it and just be concerned about expanding knowledge and when the priests tell its the right time make offsprings so that your father who was a famous warrior can educate and make them warrior too.
As much as Arjun promised himself that he'd even look and love you, you'd mainly find him with Draupadi and that was kinda known to entire kingdom and even people saw you as political alliance. When people actually did try showing affection you'd just walk away as you knew what was your work. Kunti didn't see you as anything less than her daughter if instead rumours suggested she loved you more than draupadi.
Today after a long hunt and planning Arjuna returned from a competition and all of pandavas and Draupadi, Kunti and others were on the palace outside and welcome him. And as usual (it's probably a reflex at this point) he hugs draupadi and in happiness almost forgets you exist
Yudhisthir: coughing awkwardly and signs to you "I believe you are forgetting something Arjun"
Realisation hits Arjuna but before he could even hold your hand you pull away
"I'll be by the garden if anyone even needs me" and you walk away
