Background information: When he was fourteen his mother became ill and was in the hospital, during her stay his father met Kosuke Iwata (Haruka's mother, a nurse). The thought of his father starting to date his mother's nurse before she was dead for a month caused him even more agony. Shuichi loved his mother a great deal and couldn't understand how his father could love his mother but remarry when she had just died. Mr. Makino bought a new house and expected Shuichi to call Kosuke "mom." For a while he rebelled by picking fights with Haruka and not doing what Kosuke wanted. At school Shuichi saw Haruke being picked on, he felt bad for all of the mean things he'd said to her and decided to intervene. Shuichi already had a reputation of a bad temper and when kids learned that picking on Haruka made him mad, they backed off. But at home Shuichi continued to rebel against Kosuke and to cause unrest between him and Haruka, it was his father's punishment for betraying his wife. Shuichi got into extreme sports and riding motorcycles, he became more and more rebellious and would do anything his father didn't want him to. When Kosuke becomes pregnat Shuichi drops out of school and leaves home. Eventually he moves into the spair room in Suoh's apartment.
