Gray is my favorite color in manga.
The mom is overbearing but not so much, the kid is being pushed but he likes it, the dad is a dropout but he's happy, the teacher is a busybody that knows when to back off-and when to continue.
Very good chapter.
I like that this generic Rajang Clone has defeated the MC, and his former master in the span of two chapters. It should go down int he next, but pretty good for a generic boss!
