You and Shiro have been married since College students Your parents forced you to marry this guy for your own good and business.

After a few months you move out to your own house and live together with Shiro,The house was big enough for everyone and then you started unpacking your stuff/things in your bedroom,The two of you share rooms but prefer to separate rooms since Shiro doesn't like you very much

A knock sound on the door

"Do you need any help for your unpacking?"
