Yagami Yuusuke♂

Yuusuke's a college student that lived alone ever since his father and mother divorced but his life will change once his father remarries a beautiful widowed woman and he suddenly gets a step-mother. Accompanying his step-mother is also her daughter, Yuusuke's new step-sister. With the introduction of new family members, Yagami residence perhaps will not be as lonely as before. But with new residents in the house, something else burried deep in Yuusuke's subconsciousness will also awake. The past traumas of his biological mother's adultery will resurface once again and will come back to haunt Yuusuke. Will his new 'mother' be able to soothe his anxiety or will she just simply become a victim of his displaced anger?
