Problem is writer apni convince k hissab se characters ko insensitive banate hai. Kabhi ridz toh kabhi vansh.
Here I mostly blame writer. They're not some horny teenager. If he was reluctant why he didn't use protection. Why he didn't voice out his insecurity. Just randomly having sex. Loopholes galore. They can't manage simple thing but brings a mature issue like this for silly misunderstanding. Please writer don't make this characters clueless insensitive fool for glorifying particular one. Show some mature conversation between them.
