Bihan is actually behaving in the most characteristic way. Refer to old epis u will find Bihan behaving exactly the same with Vasu. keeping his hand on glass pieces, making her wear chappals. That is what he is doing now except with Thapki. Innocent love of someone so deprived of love, love of an orphan. Not that I am not hating him. He doesnt even spare a glance at his brother, doesnt believe he deserves punishment. too much in his happy place
Thapki- I already said in Priya's post. Sometimes u just lose it if u are someone like Thapki. Not that I dont hate her lol. I dont care for either of them.
warning - I am not Bipolar just putting a case in defense
