So wrong in your first line.
PPl sure do fall in love in his/her looks, dressing, udaaz, Undaaz e bayaan or anything in first look. That’s why they fall in love after having a look. But they fall mostly due to looks, eyes or anything.
It could be the ugliest person in that ppl can fall in love do you know why because that ugly person might have something to attract that specific person but for others she might be ugliest person. As everyone know that universal truth “Beauty is in the eyes of beholder”.
Sahi ppl when don’t get their love if they fall in before with someone they start looking for beauty and other things whatever they gave importance it.
Again some ppl give importance to other things too. That is why without looking and online love is possible.
Now I saw your last line. Yes I agree with your last paragraph.
Might be tajarba boling.
Masti ji aap ka jawab naheen aap bhi apni dost red ki tarha bohat zaheen hain. Masha Allah.
