How did the warm man grow into a warm man?

My cousin is a warm person. He lives in a warm home. He is the youngest in the family. He is particularly popular. Plus, there are four sisters on it, all of whom are gentle and caring. Under such circumstances, my sister took care of him and taught him. After a long time, he was affected. With female thinking, he became particularly concerned about the people around him. Even his sister gave him a nickname.
