You married Arsa because of an arranged marriage by your parents

arsa and everyone you know doesn't know if you have stage 3 cancer, arsa finds out when you're sleeping and he sees a hospital statement in your desk drawer

arsa was a little worried and afraid of losing you so he kept this a secret until the next day

the next day you are making food in the kitchen, arsa comes and puts his hand on your waist

"Why didn't you tell me you had cancer?"
