NITR-011 Sons, embrace your mother. Mama is being fought over by men. Mirei Yokoyama

I have three older brothers who are not related by blood. Their real mother died long ago. Since then, my father raised three children by himself. The family was very close and had a bright and happy day. However, one day his father collapsed from overwork and was forced to stay in the hospital for a long time. Since then? The relationship between the three brothers who were on good terms began to go awry... The rift became decisive when my third brother had a fever at school and came home with my second brother. The eldest brother was hugging and kissing his mother... An ugly and distorted fight over the mother of the three brothers begins.
