Vol 4: Ch 244 - Splitting Personality
All of the family members didn't expect him to suddenly say that one when the kids are still around but then since they have no reactions En said it again and they can already guess why he did it, except Aya and the pair of twins excluding Ken since he heard everything.
"Shi, your Biological Mother already died"
All: ...
En: Shi, your Biological Mother already died
Aya: En?
Din Twins and Lin Siblings: Uncle En?
Ren: Dad?
Ken : (silent but just covered the ear and eyes of Jiru same with Ellyn who don't know anything but seeing her Bro Ken do that she also did cover the ears and eyes of Kaede)
En : (Ignoring that question and after seeing his son and niece doing the right thing, he smiled then he smoothly talk again to the little girl) what's wrong Shi? I told you the truth.
Shi : (Transforming to a Demoness Girl) is it the truth, Uncle En?
