I don't think that is the right concept for them to show, I don't care if its entertainment. Like I really want to see them showing romance between villain and sister, at least she said she wants her family to know about marriage.
But here is another question why should the sister believe that the new officer likes her so fast, and wants to marry her and that too in secret, is she that naive to think so.
Like seriously please. đ„±
And when the heroine was in the hero's room they were all moralistic and judgmental, I don't care if sister is not staying in the room.
Now all of you girls go make a post each. We need to maintain our status at IF as # 1.đ
