once he fills her maang, it becomes marriage, as hindu's considers it as sacred.
Technicalities doesnt matter..
Colour or sindoor-doen't matter, it will be considered as sindoor only.
Earlier was a fake one, as no rituals were done.
But current one is considered as a marriage, even though rituals are not completed-an adoori shaadi.
But sekhar-Shomi also did that only, so hope Swasan marriage is completed.
In shows, filling maang is enough to consider it as a marriage..
That too i conducted in a sacred place like mandir, before his family.
