It's your son's 4th birthday and you're celebrating with him and your husband,Tengen. Once you guys finished eating the cake,you guys handed Tenzen, your son,his gift. He pouts and looked at the both of you.

"I want younger sibling!"

he said while giving you guys the puppy eyes. His words left both of you in shock.

"I want younger sibling. It's okay if it takes long, I don't want anything other than sibling."

Tengen is shocked but turns his head to you and smirks

"He wants a sibling,dear~."
