mihir is archita's grand father and jr tharakla is billi's dad.
so jr tharakal is the guy from karan, gautam and other sons of mihir's generation (i am right, i think so) tharakal's son billi and architas are friends, among the same age am i right. so that means thakral is falling for older lady then him allmost at the age of his mom cuz thakral is allmost same age as karan and gautam or sahil.
what say guys
