Master, Laugh Once More!

"When I was fifteen, I was hospitalized. The doctor said I was not biologically related to my parents. That feeling was like… getting struck by lighting on a bright and sunny day… During that whole period, they kept talking about wanting to search for their biological daughter, and I would eavesdrop at the door. My mum didn't want to look for their biological daughter. She said she was willing to settle for what they had then and leave the mistake as it is. She wanted to continue treating me like their biological child, but my dad insisted on looking for her. My mum has always obeyed my father's words. Surprisingly, for some reason, she insisted on her stand, and the two of them argued for days. During that time, I felt terrible. I didn't want my family to be torn apart because of me, so I convinced my mother to look for their biological daughter. When I found out that she had been growing up at the orphanage and living in hardship, I felt really guilty deep down.
