Before yuuta lost his memory, he has another name. Actually yuuta was not his real name. When he gained consciousness from coma, he lost his memory and called himself "yuuta". Before the accident happened, tomohisa and yuuta had a big fight, both was hurt so much and broke up because one of them was forced by their parents to get marry. I'm not sure whom but i think it was tomohisa. for current situation, he was like running away from his family and he was so scared when he accidentally saw them later.
