THATS SOOOO FUCKING CUUUUUUUTTE (≧∀≦)ヾ(☆▽☆) ε=ε=(ノ≧∇≦)ノ
I can see that happening! Actually I kinda hope so!
legit, now I think I want him to have a really cute brother like that insteadლ(´ڡ`ლ) like when the baby is born and he finds out its a boy he will glare at him but then baby bro would bust out the old 'to cute to even be legal baby giggle', sparkles and glitter will fly everywhere and our little sadistic evil cinnamon roll will transform into a bro-con for life(≧∀≦)
Yessss it will add so much dimension to his characterヾ(☆▽☆). I'm thinking a baby brother could be someone like abel from http://www.mangago.zone/read-manga/i_became_the_hero_s_mom/ . Imagine some no name in the family tried to force the newest boy into harsh training and before his mom could react, ein will just go batshit.
Yeeees i really want that!!!(๑•ㅂ•)و✧
Lowkey wish that their future child is a boy. Subvert the expectations yk? >:) then he'll have to face himself on why he was so against having a baby sibling but not against having a little sister that mirrors his mom.
(✧▽✧)But wouldn't it be cute if he had a tiny red haired brother with the chubbiest cheeks and chased him around and said "I wanna be an awesome knight like my brother ٩(๑❛ᴗ❛๑)۶" "my big brother is so coolε=ε=(ノ≧∇≦)ノ " and he'll say and do adorable things like his mum but still have a boyish charm to him~
