Why the hell do Yuri's son looks like a bit shorter clone of her..that is her son not a daughter... right?
He has oriental blood in him. Its common for boys (men too) to have feminine feature. In the extra chapter, Yuri's also said to retain her youth look despite having a 12 years old son. Studies have proved that these are traits of the orientals. Some said that it an evolution that human undergoes long long ago. Its known as neoteny.
My god....why'd he have to be her brother ┗( T﹏T )┛
