My brother has a lover. His lover is either someone else or me. The idiom “childhood sweetheart” can be used to describe the intimate relationship between us. When we were children, we had classes in the same primary school, went to school together, finished school together, and played together. He is two years older and two grades higher than me. We live in an old-fashioned public house with a narrow environment and only two rooms. My brother and I share a room separated by planks. He sleeps on the upper deck of the bunk bed and I am on the lower floor. We go to school in the same primary school. He goes to school in the morning and I go to school in the afternoon. He comes to pick me up from school every day. He plays in the playground with me for a while before going home.
