"Sister-in-law, um…" It was not wrong to call her that, right? He placed his hand on his head and smiled, revealing his sparkling white teeth. "Hi, Sister-in-law! I'm Gao Xin, Gao Yi's younger brother. Real brother. I'm nineteen this year, currently studying at a university, but I'll be graduating soon. My dream is to be an explorer," chirped Gao Xin. However, judging from the current situation, it was only just a dream. His mother did not allow it; neither did his brother so it could only be a dream that would not be realized.
Xia Ruoxin laughed in embarrassment as she and Gao Yi were not legitimately husband and wife. Hearing 'sister-in-law' made her feel a little shy.
