The Yun family has not had a daughter for a century, but they finally had a daughter who was abducted due to an accident. In a dilapidated warehouse, the male protagonist went on a mission but brought back a baby. He originally wanted to train it to be a killer, but after raising it, he wanted to be his wife. After realizing it, it was really sweet.
Purpose: I like coming-of-age novels, but most of them are not to my liking.
