To be honest, this kind of joke shouldn't be made because it's a bit excessive.
I think it's just a joke, but Parsa is already unhappy, so there's no need to play tricks on him anymore.
And what they said is not wrong. It's really not your business. It's better not to mad, and they haven't said anything provocative either.
It's not particularly difficult to understand ... although it may require a slight
change of perspective on the part of the observer. This two sweet kids are
the same age and simply have strong feelings for each other. The foreplay
is done and their obvious LOVE is in the open... 🙂
