A twenty-year-old boy who was attending military school picked up a child. The child said that he traveled from the future to separate his Alpha father and Omega father. After hearing the child tell a lot about how bad and scum his Alpha father was towards his Omega father, he made a nonchalant exchange of pleasantries. Then gossipingly asked the child the name of his Alpha father. Wow, isn't that his nemesis of the teacher who praises his classmates? Shou was greatly amazed.

Moreover, it is known that the old enemy Jun is devoted to a certain eldest lady and is said to be engaged soon. The eldest lady is also an Omega.
