I really feel like this manga gave a second chance to dumbass-jerk characters like Sensei. Like there's hope for everyone if they change for the better. The ending was abrupt in Chapter 6 and made it underwhelming but this extra gives more light on how Sensei was willing to change his perspective in life.
Now, I just need a sequel on the children's story. Hehe~
No. 1 Seme-sama to No. 1 Uke-sama
