This is a wattpad book based on an Indian arranged marriage. So the groom is missing on his wedding day so his cousin is the one who marries the Bride. The replaced groom's name also starts with the R I think. There's this one scene where he takes her mendhi cone and replaces the groom's name with his name. They start to get along with each other until they find out the groom, Rishabh/ Rohan was missing because he met up with an accident on the wedding day. The replaced groom gets possessive and tells his wife that he must address his cousin as Bhaiyya also since she is now his sister-in-law. And he also says that once he held her hand, he's not one of those people who leaves it (he says it in hindi). I just can't remember the names or author. But I remember the some scenes. Please help!!
