Her name is spelt as Eshwarya according to Hotstar n Star Bharat YouTube channel...
So Chegu + Eshwarya =
ChegEsh
CheWarya
CheRya
EshChe
😛
None of them sound very rhythmic :( :P
This pair name is difficult to make :P
Maybe they might give each other nicknames/petnames n maybe can pair the petnames to make a Jodi name :)
Still as of now CheRya seems best :D
