If Arnav Singh Raizada cared about two things, it was the happiness of his dear sister Anjali, and to be powerful enough to buy back his ancestral home. Emotionally unavailable and unbothered, ASR's dating history was reflective of his un-callous behavior towards any other person who dared to care about him, and found themselves victim to his oozing arrogance.
This series of one-shots were written with the intention of being headcanon, and giving a peek into the breakups between Arnav and his temporary significant other of the moment.
The list of names is from Episode 13 of Season 10 of IPKKND (as numbered on Hotstar), where Khushi asks him about his pasts.
